Cons: "Overall not bad. Food service can be better but it is due to the pandemic currently. Overall excellent flight!"

Cons: "Delta flies a lot of the CRJ planes, even on relatively longer trips. Traveling first class, the seats are a little wider than in coach and have a little more leg room, but calling it "first class" is a bit of an exaggeration. It's more like what coach used to be before the days of the flying sardine cans."

Pros: "Great service"
Cons: "Messed up my luggage in Atlanta. Gate said baggage was going to domestic. Ended up in international terminal. Added almost an hour of back and forth between terminals."

Pros: "Good experience"
Cons: "Better snacks"

Cons: "I’m skinny and 5’2” and I felt squashed. Like I was in a dollhouse. The space is too small, it’s too uncomfortable. I couldn’t take my zip front sweater off. The seats and space are not proportional to humans."

Pros: "Not much"
Cons: "Being on time. Trapped in plane for 2 hours"

Pros: "We eventually got to Atlanta."
Cons: "Delta is flying a lot of commuter planes, which are pretty cramped. We usually fly first class, and the seating is essentially the same as what coach used to be. There's nothing "first class" about it. And of course, the flight was hours late."

Pros: "Crew was amazing."
Cons: "Delayed departure due to late crew arrival. Not a huge deal."

Pros: "Zee was our flight attendant and she was absolutely wonderful. Personable, attentive, and she made sure each and every person on the plane was comfortable and happy, going so far as to move solo passengers to empty rows so they could have more space. I wish she could be on every flight I take."

Pros: "I was rerouted through Detroit after it was apparent I would miss my connecting flight. The flight was good and I have no complaints."

Pros: "I did get home eventually"
Cons: "Flight was delayed. Seats are cramped."

Pros: "All the attendants were very nice. The movies were great, but ones I would have liked to watch were not on your list."
Cons: "There was no Christian music on the music section."

Pros: "Flight crew was excellent. We had the emergency exit row so leg room was awesome! Kind bar and soda we good."
Cons: "Flight delay due to the older aircraft and lack of a pilot that knew how to fly it. Bathroom needed some tending to"

Pros: "Equipment felt a bit dated. No entertainment system, which was fine with me. Skipped the offered snack. Just had water. Flight was onntime."

Pros: "Take off on time, arrived early, pleasant flight attendant"
Cons: "Had to sit on tarmac after arriving early"

Pros: "On time, pleasant and friendly flight attendant, no unexpected issues or problems."
Cons: "Grumpy gate attendants at YUL! Could not hear the captain’s comments over the PA system. Shouldn’t the volume be checked every so often? We were offered only water or coffee, bad enough, then there was no milk or cream on board, so water or black coffee... not very impressive! And there was no entertainment so I’d rate that zero but the scale only goes as low as one star."

Pros: "Snack"
Cons: "I was delayed over 2 hours"

Pros: "Easy boarding nice clean and spacious, I am tall so it is sometimes difficult to have enough space in aricraft. Staff was very nice, polite and helpfull during the long 12h flight, very nice job indeed!"

Pros: "It's a fast flight and boarding was quick."
Cons: "The terminal at LGA airlines is terrible."

Cons: "Customs never to hire more agents to work in the early mornings."

Pros: "On time, and pleasant flight. Flight attendants were first class: very competent."
Cons: "I slept all the way, so can’t say whether anything went wrong with the flight."

Cons: "Not much to read"

Pros: "I love the in-flight movies!"
Cons: "This wasn't pertaining to the flight or airline; but the TSA line was ridiculously slow."

Pros: "Good choice of video programs."
Cons: "The flight attendant took 25 minutes to appear, and had enough time for one round of service. First class, at least you should get two drinks. Fly basic economy, there just isn’t any reason to fly first class."

Cons: "Direct flight, on time arrival"

Pros: "i fell asleep until we arrive to STL."

Pros: "Not applied"
Cons: "Not applied"

Pros: "We got on the plane and it went to where it was supposed to go."

Pros: "Fligth were on time"
Cons: "My flight from Montreal to Atlanta was 2:30 min Left at 6:10 arrive at 8:30 roughly Tried twice to get to my connection earlier and get 9:30 instead of 12:09 fligth to Daytona Delta was not flexible to allow me to book saying i did not have 55 min in between fligth which i had than lear n it will cost $75.00 to change the fligth - What? Very disappointed of Delta - lost 3 hrs at the airport today"

Pros: "Same as above."

Pros: "Couldn’t find a thing."
Cons: "My husband booked West Jet by phone. They spelled my name wrong on the ticket which caused hours of delays tryng to check in...ultimately leading to our missing the flight. The time spent was around 6 hours....4 of them the were on one continuous phone call where we were bumped back and forth between West Jet and Delta. The problem was never fixed and we haven’t flown home yet. We have new flights booked on Delta but only because Delta took pity....West Jet does no refunds or reticketing. If flights are missed you're out on of luck!"

Pros: "Flight was delayed by 2+ hours, Delta (running the flight for westjet) sent 1 email about the flight being delayed to 4:45 which was inconsistent with the gate signage and agent who said 3:45, flight ended up leaving at 5:45PM. No reasons were provided beyond the incoming flight from LGA hadn't come in. Why hadn't it come in? When could we expect to leave YUL? No answers."

Pros: "Delta automatically rebooked our flight due to delays. We were rebooked on Air Canada"

Cons: "Plane kinda of old. Just cookies and coffee"

Pros: "I got to destination. Baggage claim was quick."
Cons: "Flight was delayed due to waiting for a tardy flight attendant. Landing felt a little hard. No announcement about baggage carousel prior to disembarking."

Cons: "Seats are very small."

Pros: "For a short-haul flight on a small CRJ, it was the most pleasing and comfortable flight. No delays and everyone was pleasant from ground staff to flight crew."

Pros: "Great (seemed like unusually friendly and helpful) crew. Plenty of carry on baggage room."
Cons: "Seats didn't recline. Plane hot initially and couldn't be cooled down until airborne."

Pros: "Did not eat or use entertainment."

Cons: "lack of carry on luggage space. very tight. gate agents did not care about the customers. I had to stick my bag under the seat and only half would fit so my feet did not fit with my bag. it was a back pack. I do not prefer checking luggage since I've had so many bad experiences."

Pros: "Everything was smooth. Short flight, but they offered us refills on drinks, which I've never experienced before. Polite staff, great flight. Thanks!"

Pros: "Excellent flight. Nice new aircraft."

Cons: "The entertainment system was extremely difficult to deal with. The screen did not seem receptive to the human finger and often the menu lines were small and very close together, leading to the incorrect item being selected. Finally I gave up and was just trying to put on "my flight", but it just made me take survey after survey, instead of allowing me access to "my flight" information."

Pros: "Crew service was excellent"
Cons: "Poor leg space"

Pros: "On time, nice crew."

Pros: "Plane got to NY."
Cons: "Plane got to NY an hour late due to a maintenance issue, and we missed a connection because of it. Delta staff very unhelpful regarding connections and rebooking... we got redirected to a wall of phones to call for help."

Pros: "All excellent"
Cons: "Snacks without caffeine"

Pros: "Crew most helpful."
Cons: "Always like to travel with WestJet."

Cons: "I was delayed a few houts.they could let me fly earlier."

Cons: "Small plane"

Pros: "The movies"
Cons: "So far so good"

Pros: "I slept throughout the flight"

Pros: "I liked the price for my flight however I booked using my AirMiles."
Cons: "I have travel with WestJet many times is the past and had nothing but good to say. This was my first time using WestJet Encore and was totally shocked and disappointed. The flight crew i found to be very rude with and had an attitude. The biggest shock was the greetings and all announcements were in English accept the safety rules where the pre-recorded tape was played. If asked about the return flight from Halifax to Montreal, one word to describe it "disaster". I was totally turned off with WestJet. I will for sure continue using Porter as I was always pleased with there service. As they say "you get what you pay for"."

Cons: "They tried for force us to pay for a different ticket because we had gotten a cheap initial ticket!"

Pros: "Phenomenal all around!"

Pros: "Very smooth flight!"
Cons: "None. All is great!"

Pros: "everything"

Pros: "I love flying in a smaller plane. They are usually not full in the morning and so it gave me a lot of space to relax and enjoy the flight from montreal to toronto. The crew was really nice and smilling and they made sure that my pet and I had everything we needed."
Cons: "The seats are pretty thin and uncomfortable. There is no wifi or television on board."

Cons: "Delays"

Cons: "Staff was rude and lazy."

Cons: "avoid the westjet encore flights. planes are small and noisy. if you sit next to a window it’s impossible to comfortably put both feet on the ground. if you pay for plus seating on an encore flight you’re basically paying to get on and off first. there’s no extra room and would be more fairly priced at $10."

Pros: "The flight attendants were very nice. Especially « Big John », he was very funny."

Pros: "Very friendly"

Cons: "We were delayed 45 minutes without reason, we asked to have our flights switched as we were nervous of missing our connecting flight and were told we could not switch. While we were waiting on the runway for over an hour I asked our flight attendant to check on the status of our connecting flight and she basically told us to hope for the best and that we would have to deal with it when we arrived in Toronto"

Cons: "Flight was cancelled then rescheduled on a flight that was over an hour delayed. We almost lost our connection to Hong Kong as a result. Made for a very stressful journey with 77 year old parent and 8 years old child long waiting/ tiring time and running to gate our flight."

Pros: "The seats were vinyl, not fabric - I prefer vinyl. It feels 'cleaner'."
Cons: "1.I did not like the flight crew announcing how great they (the crew) were at the start of announcements before take-off ---- If you are great, don't tell us, act like it - I found both crew members hardly engaging, one was sullen. 2. PA system was a little hard to understand anyway. Crew member should have put volume up and made sure was loud enough , but just seemed like wanted to use a 'cute' half french/half english accent to speak in. 3. Also this flight 3535 on Dec 21 Mtl- Toronto made me nervous although I fly often. Most nervous I have been because pilot took time to gain altitude after take off, and when landing had to accelerate then decelerate a number of times. Landing was (with 2 km/hr winds i.e. not much wind) almost on one wheel. 4. Food does not have to be so cheap e.g. sweet snack bar? Please bring back an assortment of nuts as they are at least nutritious. Thank you for reading."

Pros: "Nothing"
Cons: "I didn’t book the flight. Was just checking and got the confirmation of booking. Called customer service and they cancelled the booking. Question is why there is no confirmation button and how continue button can confirm the booking. Kayak need to check and advise."

Pros: "Staff was great"
Cons: "The 4hour delay on the one hour flight"

Pros: "Good service and on time"

Cons: "Snack was very minimal with no selection or option to purchase more."

Pros: "Quick boarding and quick to disembark."
Cons: "tiny! you get what you pay for with a turbo prop."

Cons: "You should hire agents who don't lie to passengers. That's not a good reputation 4 the company. Have an office for the baggages where passengers can address their issues."

Pros: "The flight was on time"

Pros: "That we didn't crash."
Cons: "Two hour delay, disinterested CSA when checking in, clued-out flight attendant, GSA's didn't know how to gate check luggage. Will try to never fly another WestJet flight again!"

Pros: "- Flight was on time - Friendly crew"
Cons: "- My flight was from Montreal to Seattle with a connection in Calgary but the agent at the check in in Montreal was unable to confirm whether my luggage would be transferred directly to Seattle or if I had to collect it in Calgary and check in again. The crew should know or be able to verify the information in their database or somewhere at the departure not only when I arrive in Calgary! It adds a stress to the customer not knowing. - Flight of 4.30 hours and no free meals. - Impossible to use my hear phones in the plane so I couldn't hear the TV channels. I was also expecting movies and series like in Delta."

Pros: "Flight was on time."
Cons: "Seating was very cramped, uncomfortable."

Pros: "The airplane being pretty small, boarding and getting off was fast. No issues or delays either."

Cons: "The flight was delayed by 2 hours. So we reached almost at midnight to Vancouver."

Pros: "Actual flight went off without a hitch to Vancouver no delays in air."
Cons: "We were moved gates which is understandable, however once moved the estimated time of departure was constantly changed and missed. There was a reasonable cause for delay (cleaning up puke) but took abnormally long > 2hrs. Staff did not seem to be really giving it there all (understandable as it was late and they were probably tired)."

Pros: "Crew was great. Flight was on time."
Cons: "This older plane had tiny seats in the seat backs. My phone screen was bigger. Thought we might get a meal on a flight of this length and at this time of day."

Pros: "Nice and professional service."
Cons: "Having to pay for my checked-in bag."

Pros: "Customer focus and service"
Cons: "Nothing"

Pros: "Free wine and beer."
Cons: "Our flight for Toronto on Sept. 5 , # WS589 was delayed of about 1 and half hour; so, me and about 20 other passengers missed our connection in Toronto. The crew said that Pearson airport was on a shut down due to severe thunderstorms. But the weather was nice and sunny when we arrived Toronto; in fact my connecting flight ( Hainan airlines HU 7995 had left 20 min. earlier- on time- for Bejing. The crew in Westjet plane told me that all airlines were delayed in Toronto airport due to bad weather , and so that I would not miss my connecting flight."

Pros: "Leg room"
Cons: "Unprofessional staff. Made a mistake during boarding that caused 2 hour delay"

Pros: "Friendly staff"
Cons: "All flights boarded late, they ran out of food for purchase on long flights and the seats are uncomfortable."

Pros: "Montreal to Toronto the crew and staff was great and in a good mood and very pleasant"

Cons: "Connecting flight was cancelled."

Pros: "all the service was very good to us"

Pros: "The fact that air Canada had a flight around the same time"
Cons: "Kept delaying with no clear idea of when we'd actually take off"

Pros: "The service was nice"

Pros: "Made it to toronto in time to catch my next flight"
Cons: "Flight was canceled Next flight was delayed 30 mins"

Cons: "TWO gate changes and several delays later, we finally got to Toronto."

Pros: "The assistance of the WestJet agent"
Cons: "I was held by the American immigration for over 30 minnqnwnnni missed the flight"

Pros: "Much friendlier than their Canadian competitors. Efficient boarding. Caring crew: One flight attendant gave a passenger part of his own breakfast when she wasn't able to eat her nut-containing snack because a nut allergic passenger was on board. Like the power stations at each seat with USB and AC connections."
Cons: "The coffee was very weak. More like brown water than coffee. Food choices were very limited. The entertainment system, available by App on my ipad, worked, but intermittently."

Pros: "If I could choose my seat"

Pros: "Our flight attendant was very polite and with a great attitude."
Cons: "The pilot arrived late because he went for a Tim Horton's coffee (I know that because I was in first row and I heard the flight attendants talking about that). Then, after he finally arrived with a tray full of coffees, there was an issue with the jet's computer and had to reset it and we had to wait even more. When we finally arrived, our Gate was taken by other plane already and we had to wait (more) for the first one to be available for us. Then, when we finally got our Gate, there was another issue, now with the "finger". They weren't able to move it and connect it to the plane to get off of it. So we had to wait AGAIN. And finally as soon as we got off the plane, they were supposed to give us our carry ons on the aisle (Because it was a small plane CR700) , but again, we had to wait almost 10 minutes so that they could send the luggage... To make things worse, I had a first class ticket and I couldn't get the perks of it at the airport. Because they said I wasn't flying in an international flight. Come on?! Canada->USA->Mexico is not International??? You lost me AA."

Cons: "Seat space"

Cons: "Delayed three hours with no communication or compensation. Poor customer service"

Cons: "Person in front of me had seat reclined from take off to landing. Nobody checked. Nobody told him it had to be upright during takeoff and landing. I believe that is a safety issue. Isn’t that why the flight attendants are there?"

Pros: "Crew nice- flight smooth"
Cons: "More leg room"

Cons: "Better communication about handicap persons. I called twice and notified two people about my mom and her wheelchair but no one tells the gate to put a ramp up to the regional jet on the tarmac. Three ring circus as usual ."

Pros: "Crew friendly and accommodating, even on short flight"
Cons: "Good - no complaints."

Pros: "Service was good"
Cons: "Nothing"

Pros: "Nothing"
Cons: "Flight was late and caused me to miss my flight to Dallas."

Cons: "First flight delayed 45 min, then cancelled. 2nd flight 3 hrs later."

Pros: "Left on time, service was good."

Pros: "Clean, Friendly flight attendant"
Cons: "I don’t understand how a brief meaning less than 30 minutes thunderstorm can cause a five hour delay. Every time I take the route from DCA to STL American is always really late"

Pros: "crew was pleasant"

Pros: "My flight was fine - I paid for a Premium Seat, which also allowed me a premium boarding position, which I highly recommend for anyone flying. The seat was comfortable, the staff was very friendly and I really liked the in-flight entertainment."
Cons: "At the DFW security post for my gate, there was NO TSA-pre. That service stops at 7pm. I would think at a major airport like DFW where American Airlines has a hub, they would make sure to staff that longer. Just getting to keep my shoes on, while having to drag all my electronics and liquids out, take my coat and belt off, etc. is not acceptable. AA should put the pressure on DFW to treat their customers better!"

Pros: "Great pilot. Outstanding control over the plane. Arrived an hour and a half before originally forecasted three days prior."

Cons: "Flight was delayed almost two hours due to crew staffing issues."

Cons: "I asked for water and juice, they just gave me juice"

Cons: "Nothing to dislike"

Pros: "This flight is the normal nonstop from Mia to StL. The seating is tight but not completely uncomfortable."
Cons: "I just had knee replacement 4 1/2 months ago. It was difficult to fully extend my leg under the seat in front of me because the space between rows has shrunk to include more seating."

Cons: "the fly got delayed for more than 3 hours."

Pros: "The crew was great! They did big effort to speak in Spanish! And also they are kind in every thing!"

Pros: "It was easy to travel"

Pros: "The middle seat was empty I had an aisle seat. That was wonderful."

Pros: "Great staff."
Cons: "The hour delay due to maintenance and fueling."

Pros: "On time"
Cons: "Boarding numbers"

Cons: "Seemed to be an unnecessary delay in departing a half hour late"

Cons: "I nearly missed my flight because I did not have a seat for a flight that I bought a ticket for at full price. Which, would lead one to believe that I would have a seat on said flight. However, coming to the gate an hour before boarding the personnel working gate the said he was having computer difficulties and could not get me a seat and it would be 10 min. I continued to return till boarding to find out I had no seat and I was on standby. Upon going to customer service they replied the airline oversold tickets and every airline does this as if to make this practice ok. Well being in sales myself and if I were to sell x amount of product to one customer ( or several) I better make sure I have it all there to deliver. People rely on you schedule wise. It nearly shot a meeting I had to make in the foot. Very disappointed with the airline and the way things were handled."

Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."

Pros: "We boarded fast and the flight was smooth. The crew was very friendly."
Cons: "The sears were a little uncomfortable. They went terrible but my back started to go out on my 2 hour plans ride."

Pros: "Our flight was cancelled"
Cons: "Our flight was cancelled And rescheduled and we were not notified. We missed our flight. The next flight was the following day. We missed a day of vacation and $500 a day hotel fees. We felt we should be reimbursed for our flight but the person we talked to wasn't too helpful."

Pros: "very friendly staff"

Pros: "Nothing to expect from Domestic fight."

Cons: "Boarding was chaotic, with people sitting in wrong seats and walking the wrong way down the plane. Crew were not especially friendly. I know it was at the tail end of a long Sunday, but it wasn't impressive."

Pros: "Plane was ancient"

Pros: "Good"

Pros: "Entertainment, 110 plugins for devices, internet."
Cons: "only free meal option was cinnamon cookies."

Pros: "All flights were on time Greatly enjoyed the trip"

Pros: "On time, arrived early."
Cons: "Seats too close in front of you."

Cons: "Again out of snacks and she skipped our row for drinks. Again small issues but what else are they doing?"

Cons: "Attempted to make my connection which was in another terminal. Could not get onboard as they shut the doors. My rerouted flight was in a different terminal. Overall a very disappointing travel experience."

Pros: "It took off on time and life was good."

Pros: "The plane has improved greatly with their comfort and leg space"
Cons: "With checking my luggage my bag fee was waived a total of seven times this trip because I'm a military wife to see my husband overseas who is serving a year in Saudi Arabi except this past time on October 2nd at DCA airport. Spoke with the Supervisor Ralph who stated it was against policy. How stringent is this policy if it was waived seven times previously? Policy needs to be reviewed with entire staff. I will no longer use American Airlines because their military convenience and policies no longer seem to favor the military. My husband also after speaking with him will also no longer use your airline including all his members he overseas when they return after their year tour."

Pros: "The people"
Cons: "The seats are too small I'm 6'1 and that's not that tall"

Cons: "Nothing"

Pros: "I landed safely"
Cons: "The infotainment system didn’t work. Headphones connection is faulty. Everything else was ok."

Pros: "yes"
Cons: "eat"

Cons: "They didn’t put enough fuel in the tank and the pilot only noticed when we were next in line to take-off so that led to a 30 minute delay. Some terrible seat designer put the call button and light control on the armrest exactly where your elbow rests so every few seconds you would here a call bell."

Pros: "It appears that Air Canada is doing the correct thing for passengers who have reserved their seats in advance....after many years of not applying their written policy of making them board after business class/disabled passengers/passengers with young children, they have created Zone 2 boarding which permits passengers with reserved seating to board immediately after them, therefore guaranteeing them overhead bin space. As we all know, a lot of passengers board with much more than one carry-on, which is a plague when boarding."

Pros: "More opportunities to eat Tim hortons"
Cons: "Having to wait 24hra to leave Canada"

Cons: "No AC for the first 30 minutes after boarding so it was wacky hot and stuffy."

Cons: "Air Canada was the only airline flying to ny that was delayed."

Cons: "I made a reservation for my whole family and selected seats four month ahead (we reserved 1A, 1B, 1C, and 1D). One day before the departure, United informed me that one of my kid had to be moved to 11B a part from the rest of family due to a flight swap. When we started boarding, I noted someone else was sitting on my seat (1D) with his own boarding pass with 1D written. United crew politely asked if the gentlemen was willing to move to 6B, which his original seating in the system but he refused to do so. We' also personally explained to him that if he can yield the seat so that our family could sit together due to my wife's medical condition but he would not cooperate. I noted Those gentlemen on 1D and 1C are either buddies or coworkers. The crews were looking at each other without offering a solution. I ended up telling the crew that I could sit on 6B so that the plane can leave. The departure time was 20 min late u related my seating issue and de-icing took another 40 min. I am a Global Service member and I am very unhappy about the way the whole situation was created and handled by United."

Pros: "The flight departed early and arrived early, good flight attendant service"
Cons: "Long wait on the cold jetbridge for our carryon baggage, tight quarters on the plane"

Pros: "I had absolutely no complaints about this trip"

Cons: "Electrical service was spotty"

Cons: "Luggage took >1hr. Flew w Copa - always got bad seats when on United flights"

Pros: "Crew was very nice under difficult conditions"
Cons: "Flight was late, baggage was damaged"

Cons: "Far away Gate"

Pros: "The flight crew was courteous and efficient."
Cons: "The boarding time lasted an hour as the front desk staff at the gate insisted that I needed a visa travel document for my connection in China (multiple leg journey). What they failed to realize is that nobody needs a visa for China if they’re connecting in transit. It took a phone call and 3 staff members to sort things out. Not something that I want to deal with at 5:00 am. Moreover, due to the de icing, the flight was late and i just made it to my connecting flight in Newark. It was quite a hair-raising experience overall."

Cons: "flight was over two hours late because of a late incoming plane. That may be for good reason, but we weren't told until less than one hour before takeoff. It doesn't make sense that the airline just found out one hour before takeoff that the flight was two hours behind. We should have been told sooner about the delay, while we had other choices of alternate flights."

Pros: "Nothing"
Cons: "Smoke on the plane crazy delay"

Cons: "This plane was awful. I don't know how anyone who is not miniature sized could be comfortable on this plane. I am 6' 1" and ~ 200 lbs, not huge by any means, but not tiny. I legitimately could not stand up (so I had to sort of slouch walk down the aisle to find my seat at the back of the plane), then the seats themselves were so narrow that I ached terribly when seated in any position for more than acouple of minutes."

Pros: "On time"

Pros: "That the flight was earlier then Expected"
Cons: "Bag fee"

Pros: "Seats were very roomy and pilot did a great job!. Boarding went great!"
Cons: "We were stuck on tarmac but this was weather related. No gluten free snacks. Some crew was nice others less so."

Pros: "Crew was nice"
Cons: "Flight was 4 hours late. The seat was so small, I could not open the tablet (folding tablet in armrest). I am 6" tall and medium built. That tablet can only fit a kid"

Cons: "Delayed delayed delayed"

Pros: "Flight was ok"
Cons: "It was late"

Cons: "Flight was 3 1/2 hours delayed. Missed my original connection. Missed the second connection because (as the attendants told us) they were unable to get ANY flight information to inform the passengers of where their connecting flight was. They were also pretty snotty and acted like it was our fault that we might miss a flight. I'm now sitting in Houston for the final flight of the day."

Pros: "It was fast & we didn't die we're the only good things"
Cons: "The Flight attendant was rude and mean , the plane was small and old .. But most of all he flight attendant ruined the flight for everyone. I even heard people saying she was mean as they were getting off the flight. I think her career as a flight attendant has ran its course (she was pretty old also)"

Pros: "I really liked that the flight attendants came through to offer drinks and pick up trash several times and not just once, even after the turbulence that we had. I really liked the alternative wafers instead of the traditional trail mix or peanuts."
Cons: "I have no complaints with my flight, but I would sincerely appreciate if United offered some kind of neck pillow or a thin rolled up blanket for extra comfort on longer flights (5+ hours). These minor comforts are forgotten when packing my own bags when worrying about everything else."

Pros: "Still not in stl"
Cons: "Still not in stl"

Pros: "The plane was unboarded due to mechanical problem but a new plane was found and within an hour we were back on board. Appreciate the quick turnaround."

Pros: "Nothing. It's just ok."
Cons: "Nothing, just ok."

Pros: "UAL customer service horrible. Would not pay for a hotel room we needed due to UAL canceling our flight. Customer service reps few & far between UAL bus at Terminal C gate 71 at 10p 9/30/2016 had rude employees refusing to acknowledge is or help rather they listened to music on their cell phones. FIRE THEM."

Pros: "friendly flight crew. good informations nice plain"
Cons: "- entertanment only with pay??? this is a step backwords...."

Cons: "The snacks are too small."

Pros: "Bad good, good service but 5 hours delay"
Cons: "The airplane food and the delay in Chicago"

Cons: "STINGY DRINK SERVINGS TINY SNACK BAGS"

Pros: "2 hours delay. Seems a trend with United domestic flights (technical problems, not the weather issues). United should review flight schedule to consider the delay so the passengers don't have to be a victim of those delays."
Cons: "Delay!! After traveling 20+ hours internationally, 2 hours delay on the last leg really is a big burden."

Pros: "Can't really remember if I liked anything."
Cons: "Unfriendly crew. Flight delayed by more then 2 hours. We were moved from gate to gate 2-3 times. Totally disorganized."

Pros: "Nothing"
Cons: "Flight got camcelled made me late to duty station"

Pros: "Staff was friendly"
Cons: "Delayed for 2 hrs after my 4 hr layover"

Cons: "Some other carriers offer wifi inflight service free of charge. I tried connecting to wifi in flight with no success several times."

Pros: "newer plane. more personal space per seat"

Cons: "Our flight got canceled due to airport issues at our destination. United canceled the flight but had no alternative flights to get us home. Flights the next day were full. Took over an hour with the service desk to reroute tickets to cancel them and to get bags back then took two hours at baggage claim to get the bags back. Customer service was basically useless. After all that, we didn't get any of our money back! I will be avoiding United airlines. Flight cancelation was not their fault but the way they handled the rest of it was embarrassing."

Pros: "Never on Air Canada again. Food was miserable. They literally told me that they ran out of food (on the flight from Montreal to Casablanca). No kidding. They told us that the flight was full and no more food was available! When we asked for water, they did not bring water. I am not sure if they were out of water because the flight was full! That would be something! Bathrooms were not usable. Utterly dirty. My six-year old daughter refused to use the bathrooms. Water was flowing and the smell was horrible. They should clean that. I can go on but what is the point???"
Cons: "The list would be too long. So, what did I like is a better question in this case. Honestly, I am not even sure if I liked anything. I mean some people were nice, but why? Do I expect people to be rude? I mean, I need to like something extraordinary, something that others don't do. I can't remember anything remarkable. Just nothing."

Pros: "The young lady who was the flight attendant was very nice and tried to make a very bad situation somewhat bearable. There were a number of children on the flight that she was very attentive to. I hope united treats their employees better than they treat their passengers."
Cons: "The flight was delayed for 4 hours. We were told to proceed to the United terminal in spite of the delay. There seemed to be no effort to inform or assist us. There was very little to do in this terminal but wait to see if our flight would eventually come. There were other United passengers in the terminal who were also waiting for overly delayed flights. eventually, we had a plane that was extremely small, cramped and uncomfortable. United seems to consistently oversell its seats and then tried to get people to give up their seats. Very poorly managed airline with bad customer service. Sadly, I have to say that I have never had an acceptable experience on a united flight. Will NOT take another United flight."

Pros: "I liked that they waited for me because my flight was late getting in to San Francisco."

Pros: "No much"
Cons: "Take forever to load. No entertainment. Hard, uncomfortable seats, no food. Kept talking about "premiere plus" benefits. Why does it cost $80 to have not bad service?"

Pros: "flight was on time"
Cons: "airport gate lady would't let me run to the bathroom and quickly return for my checked carry-on for "security reasons." Then I heard about 4-5 people being paged to come pick up their checked carry-on luggage."

Cons: "lost our bag, crying babies, uncomfortable plane"

Pros: "I was comfortable and I didn't die."
Cons: "N/A"

Cons: "It was not on united because it kept getting delayed."

Cons: "System was screwed up, boarding was a nightmare."

Cons: "Cramped space."

Pros: "Good"

Cons: "TV was broken"
