Pros: "The soda did not taste bad."
Cons: "Flight Delayed by 2 days, only offered hotel voucher for one day, despite being told we would get vouchers for 2 days. Customer service made no attempts to make the situation right. Employees at the airport did not know what they were doing, gave lots of misinformation. Upon landing, we were refused our bags despite being stranded for multiple days. Terrible experience. I urge you to stay away."

Pros: "Tried so hard to be friendly & cheerful to flight attendants & they were pretty humorless."

Cons: "Delayed over an hour then cancelled last minute, rebooked on a flight the next day that didn't leave until noon, had to call into reservations to get on an earlier flight on another airline"

Pros: "The connecting flight was with air Canada. In general the flight was fine. Landed on a Saturday afternoon."
Cons: "What was not fine was the horror at the other end when air Canada lost my bag (which had my suit and prescriptions) and couldn't tell me where it was or when it would be delivered for over two days of calling between their service centre and one the ground people at Boston. The call centre was in India, no one in Boston would tell them what was going on. It should not take three days to sort, when the bag had actually been sent on the next flight (on Saturday evening) after the one I took. Fortunately, was able to borrow BP medication from a relative and ultimately had to spend money to buy new suit and clothes before bag finally appeared because I had business meetings for which I needed appropriate attire. Every other airline I gave flown where my bag was delayed was always delivered in 24 hours. This was not Brussels airlines fault, it was the fault of air Canada."

Pros: "The flight from Toronto to Boston is extremely short, about an hour. I don’t feel as though I can rate the food since I didn’t buy any, it just doesn’t give me an option to not rate it. It was a completely full flight. It was as comfortable as can be. It’s a smaller plane so you feel everything but the captains were good flyers."
Cons: "I’m not sure if this is something I can really complain about but I wish the flight attendants would’ve spoken a bit lower. For a plane where half of the people there had missed their connecting flight and were put on a 6:30 am flight, I don’t think we wanted to hear about their detailed personal lives."

Pros: "That we eventually got a flight home."
Cons: "Being stuck in Boston and Ottawa for 2 extra days and adding around $1200 on to our trip in hotels alone (I was travelling with 4 kids on a school trip and my wife). Additionally, we didn’t find out the flights were cancelled until we arrived at the airport. Apparently, they had been cancelled 2 hours before but there was no notification. Air Canada offered no help whatsoever and the guy at the “service” desk in Boston literally said there was nothing he could do to help. Not even find a new flight. Spent 90 minutes on the phone trying to re-book, plus re-booking hotel along the way."

Cons: "Everything was seamless and i have no complaints. My return flight was cancelled amd i was automatically put on a different flight, and instead of waiting more than 2 hours from boston to get to canada, i was put on an earlier flight for which i am thankful for. However we couldnt take off as delta was clogging up the way to the runaway so ended up waitimg an hour to taje off which was ridiculous. Hope delta hires more ground crew so that others arent inconvenienced in the future."

Pros: "Love Air Canada. Great service and good entertainment"

Pros: "I flew through Vancouver from Boston on my way to Brisbane, Australia and back. I was nervous at first because of the 2 hour connection windows. This might be a testament to Vancouver Airport more than Air Canada, but the flight home after an initial 14 hour flight was pain free. Boarding was fast (the flight wasn't full) and we ended up pulling away from the terminal early. I slept most of the flight so I can't really comment on food. The entertainment was the same as when i left for Australia, which was ok. It had a decent variety to select from."

Cons: "Still waiting to try to get on a flight via the standby option, and even that flight keeps getting delayed and the gate was changed. The whole trip has been a clusterf***."

Cons: "I missed my flight due to new regulation eTA. why not warning people when purchase the ticket?"

Cons: "First it was delayed because of the aircraft, then it was delayed some more because of the bags on the plane but no passengers - bag owners . Then it was delayed because the ramp crew could not be found to remove the bags. Then it was delayed because of the weather ..."

Cons: "Both flights were over 1 hour late. Weather was fine so difficult to understand delays."

Cons: "We got delayed, but this was not the fault of the airline. My bags were put on the wrong flight as well"

Pros: "Pilot was able to make up for delayed departure and flight arrived on time."
Cons: "Plane needed better cleaning - Lots of stuff (food, paper, dirt) between the seats. Entertainment system not working properly - screen kept going blank."

Pros: "Short flight - no issues"
Cons: "N/A"

Pros: "Nothing in particular stood out in Montreal or the flight to Boston, as better than average...meh"
Cons: "Our Swiss crew told us over the loudspeaker several times that "even if connecting we still need to get our luggage" which turned out to be false as our luggage was transferred to the Boston bound plane automatically... We were ushered out as a group to a connection security check which required electronic kiosks to be used for scanning our passports photos and fingerprints... They fraught with malfunctions then after waiting in line for s while we did the whole check all over again with s human security agent in s booth... There were only 2 security agents in the booths as well but there really needed to be several more to keep the line moving quicker... After security we walk directly out to departures but no mention of baggage claim, which was fine had we not been misinformed by Swiss initially... We ended up inquiring several times with SirCsnsda staff until it was clear Swiss had misinformed us."

Cons: "I did not take it."

Pros: "The flight itself was fine, free WiFi on board, movies to watch, stewards and stewardesses on board were very kind and attentive."
Cons: "I was originally flying WestJet, and the 7:05 AM flight I booked was cancelled. I hopped online and booked the 8:10 AM flight via Air Canada back to Boston. First, the flight was oversold, so only AFTER I was able to check my bag did I learn that I was flying stand-by. Completely nerve wracking. If I had known in advance I would have booked with another airline. I was able to get on the flight thanks to some volunteers who gave up their seats on the 8:10 AM flight for the next flight out (10:10 AM) in return for some monetary compensation. I arrived in Boston, and after waiting for 45 minutes, I learned my bag was put on the 10:10 AM flight rather than the 10:10 AM flight, but only after dealing with a snappy and disrespectful check-in attendant that seemed to not believe me that my bags indeed did not arrive. The office for baggage services for Air Canada was vacant and locked next to the carousel. Myself and a couple of other travelers, upon getting to the check-in counter and explaining the situation mistakenly lumped us all together and said "okay so you're all traveling together and your bags need to go the same place". Me: "No, that's incorrect, we are not related or traveling together, we just all have the same issue--none of our bags have arrived". Other Air Canada representative, who up to this point had not been involved in the exchange: "She didn't ask you if you were related, she asked you if your bags were lost" and then proceeded to roll her eyes and walk away from the counter. I suppose she misinterpreted my concern for rudeness and felt the need to put me in my place. Granted, my early morning flight cancellation and the stress associated with flying standby had nothing to do with them, but the attitude I was given as a concerned traveler whose bag was potentially lost was completely unwarranted. Compounded with the frustration of the entire morning I cannot describe how infuriating this exchange added up to being. I was told my bag would be delivered to my home by 4 PM that day. No bag. Got a phone call at 7 PM - they'd be there in the next hour. 10:00 PM and going to bed: No bag. I gave up and prepared to make a claim in the morning. 8:30 AM Sunday morning - my bag is sitting on my front porch wrapped in a trash bag. What a fiasco."

Cons: "Flight crew not helpful. Despite empty space in first class overheads, would not allow coach passenger to put anything there."

Cons: "Flight was delayed. They lost my baggage. TV in my seat didn't work and they didn't do anything about it."

Pros: "Spacious flight Cozy environment Comfortable sitting"

Pros: "-Staff offered free things like headphones and 15 minutes of wifi access to compensate for multiple delays -Cheap! -I was rescheduled to this flight after my previous flight was delayed and prevented me from taking my original flight back, but I was moved up to boarding zone 3 in return"
Cons: "-Significant delay prevented me from checking in to my room, which was highly inconvenient. Fortunately I had a friend who was willing to have me, but if not (and because the nearby hotels are filled up due to the beginning of freshman orientation at my college), I would have had nowhere to stay after 13+ hours of flying and exhaustion. This alone significantly hurt the experience."

Pros: "Everything excep boarding on return flight."
Cons: "Delay on return & boarding was really slow! Not sure if it was the computers or attendants."

Cons: "Our inbound flight was two hours late. When connecting through Toronto, they lied to us. They said that the outbound connection was on time, that we'd likely missed it. Then, after standing through their requisite customer service line with only one open desk for two full flights, we were told to sprint through customs. We arrived, breathless to find the connection was delayed. We were told that they don't post the delayed connections for fear that passengers won't run or that U.S. customs will close. Uncommunicative and untruthful, their service is atrocious."

Pros: "Flight crew was friendly. They were dealing with a lot of crabby people due to a 4 hour weather delay. They handled it, some better than others."
Cons: "I checked my bag. It got soaked. I am talking drenched like dumped in a lake and left there for the 4 hours we were delayed in Toronto. When we contacted air canada the luggage complaint rep told us to complete an online claim. We haven't heard a peep out of Air Canada in a week. Unacceptable Air Canada. You must would at least acknowledge that something was done wrong by a baggage crew even if they aren't on your payroll and on an airports."

Pros: "Nothing"
Cons: "Absolute joke of an airline with zero customer service. I would never travel with them again and would recommend anyone else not too."

Pros: "The gate crew in Toronto was outstanding.Very helpful in making sure we made it on to the Boston leg."
Cons: "We were at the gate in Toronto for the Boston leg but the computer assumed we would not make the connection because our layover was less than an hour. We booked through Kayak but were not told that the layover was too short."

Pros: "I liked that they were quick and nice service."
Cons: "No games for entertainment."

Pros: "Crew was efficient, and the plane was on time."
Cons: "The seating and luggage storage was a bit cramped."

Pros: "Nothing"
Cons: "After waiting 30 minutes after our boarding time, I got an email on my phone saying the gate had changed. No one at the current gate knew anything about it and I went to ask but no one could be found. I asked a man sitting behind the gate, who happened to be the pilot, and he also knew nothing about it. Needless to say, the gate changed and absolutely nobody was told about it. 2 hours later, our flight finally took off, and I was thanked by the pilot for getting us to the right gate... At least he provided a little humor to the situation! Plane also wasn't cleaned, pretzels and trash all over the floor."

Pros: "This was the smoothest flight I've ever had. Great pilot."
Cons: "It was a bit delayed."

Pros: "The crew was fantastic, really lovely and chipper!"
Cons: "There were only pretzels as a food option and I have celiac disease so I'm allergic to gluten. You can't just have one food option stop skimping. ALSO - I was put on a standby list which is entirely unacceptable. I purchased my ticket, therefore I should have a seat on a flight. Luckily in the end I was printed a ticket, but being on standby was just bullshit. Totally unacceptable."

Cons: "DELAYED"

Pros: "It left ontime and got me to where I needed to be."
Cons: "Pretzels are gross and dry. Jet Blue has much better snack choices. Overheard bins were really small on this small aircraft."

Pros: "For a small aircraft like that, it was really comfortable."

Cons: "No cookie."

Pros: "It was a short flight but smooth and on time."

Cons: "Crew stopped severing prematurely. He said we were about to land and failed to serve my row and the one behind me. In the end we still had 30 minutes before we started the initial descent. When the person behind me spoke to him about it the steward was rude to him."

Cons: "The woman at ticket counter was rude and not helpful"

Pros: "It was a pleasant experience , the whole travel"
Cons: "Nil"

Pros: "Great flight, entertainment system, flight staff made me feel at home"

Pros: "I enjoy flying and being in the air at high altitude in any air line. Away from everyone else and with a new family who are flying with me."
Cons: "The charge per bag is ridiculous. It should be included as part of fare paid. Understood another bag charge as a separate fee."

Cons: "The flight was late"

Pros: "short flight with a good seat. fast baggage service"

Pros: "Despite the crew being on strike, the only attendant on board did an excellent job of handling everybody's needs."

Pros: "Direct service is nice! Clearing customs in Ottawa makes life easier."
Cons: "Buttery pretzels in both directions that are way too buttery. Crew is never overly happy to be there."

Pros: "This flight always takes off and lands on time, and has a friendly flight crew."

Cons: "The screen at my seat did not function properly."

Pros: "amazing crew, very clean"

Pros: "It was a regular nothing different flight then what was expected."
Cons: "Need to develop the entertainment system to become at least minimumuly adequate. I have learned to treat these flights as buses in the air."

Cons: "It began going downhill at the United Lounge, where I put two chairs together to get a little sleep since my flight was scheduled to leave at 12:30am. I was summarily woken up and told that it wasn't appropriate to sleep in a lounge. I complained at the front-desk (politely) and was told ... "This is a lounge". Oh and yes, the Wifi wouldn't connect and the food was stale ... so I left, and found a very nice sofa in the concourse. On the flight, service was non-existent, whoever was in the galley was clattering things about, despite the fact that this is a short red-eye flight ... the coffee was awful. The steward forgot to give me my coat and I had to ask twice AFTER we landed and were leaving the plane to get it. By contrast, Lufthansa has daybeds and a special quiet area to snooze, and offer pillows and blankets. Clearly, the Germans are louche compared to Americans."

Pros: "A competent cross country flight."
Cons: "Very cramped. Having 2 aisles did help."

Cons: "All of the restaurants in the airport have changed to this "high-end" bistros. No fast food anywhere except the premade wraps and stuff at the kiosks. If you need food fast don't try to sit down and eat. My sandwich took 30 minutes to come out. Food was ok."

Pros: "The check in was great. The staff was very helpful."
Cons: "The plane was very small and hot. There was no space for even my legs."

Pros: "Movie deal was enjoyable. But a tough week for the friendly skies!"
Cons: "Mechanical caused me to miss my connection. Exterior of 777 had paint peeling off the fuselage, which is a bad sign. Plane needs an overhaul"

Cons: "Uncomfortable seats, inefficient food service and pricey, and entertainment is a rip off."

Pros: "not a damn thing"
Cons: "Weather delays are a typical part of travel. What's not typical are 5+ hour delays and sitting on the tarmac and watching your connection take off without you. First Class seats morphed into Economy center seats the next day, with nary a hotel room in sight. Thanks for nothing."

Cons: "Great employees!"

Cons: "Flight was delayed Arrived two hours late No food or beverages Staff stayed seated"

Pros: "Super"

Pros: "Dependable, fast, clean"

Pros: "Movies were great"
Cons: "Need more snacks on a long flight"

Cons: "Even though I downloaded the app, the WiFi wasn't available so there was no entertainment. Also, the flight was delayed over an hour."

Pros: "Plane took off on time and landed early :) smooth flight despise weather. Overall great flight"
Cons: "The flight attendants didn't smile much and were very bossy."

Cons: "4 hour 20 minute delay to change part. Since last flight of nigh plenty or the planes could have been substituted while part was switched overnight on this one."

Pros: "Clean plan and ok seats"
Cons: "No entertainment, no wifi available, checked carry-on bag because they said there was no room, which was not true, boarded plane late which delayed the filght by 20min for no apparent reason... Crew was not friendly and did not follow captains orders when we hit turbulence as some members would not remain seated which lead to head crew member to make a public announcement to the crew to remain seated and follow captains orders."

Pros: "I like that the flight was quick!"
Cons: "2 babies were on board. Cute but screamed the whole time! Not pleasant at all!! When booking passengers should be able to view if another passenger with baby will be on board!"

Cons: "Just got off a SF to Boston flight on a new looking 737. It was the worst, most uncomfortable flight experience of my long life. The seats are narrow to the extreme (BTY, my doctor tells me I'm under weight for my 5/7 frame), and the leg room is practically non existent. You can't stand up if the person in front of you has their seat inclined. Shame on you United for packing us in this tight. There are tv screens on the back of the seats but you have to pay for tv and movies, unlike JetBlue, where tv is free. It would at least have been nice to have the flight path shown at no cost."

Pros: "Boarding was easy and fast. Flight crew friendly."
Cons: "Being stuck in airspace for an hour. Caused our flight to land late, making me late for a meeting."

Pros: "The crew was great. The flight was better than the outgoing leg because of the different aircraft and the crew."
Cons: "The seats were too tight as usual. Too many people for a small space."

Pros: "a complete circus~! Reservations were messed up by someone and caused me to miss my direct flight. Overbooked."

Cons: "I am very sick man. Airline was supposed to have wheelchair waiting for me. They didn't at departure or arrival. I almost missed my flight waiting for it so I just walked. Which almost killed me. I have doctors appointment tomorrow. Very awful airline"

Pros: "There was not one glimpse of positive in this experience."
Cons: "Upon arrival to Newark there was no gate agent available to check in with for the first two hours of the delay. In the air there was no food or drink service. The plane loaded at 1230 but did not push back from the gate for almost another hour. Upon arrival in Boston we spent near another hour on the tarmack waiting for a gate free up with very little comunication. I got to Boston 5 hours after I had intended to with no ability to give my rid from the airport any info for when I would be getting off the plane. The whole time dance moms rotated between a different show but must have come on 3 times with no ability to shut the screen off and take a nap. No compensation was offered in any way."

Pros: "Good flight arrived early and upgrade available"

Pros: "Someone stole my seat and asked me to sit in theirs, but ended up being a window seat!"

Cons: "It was 4 hours late."

Pros: "The pilot was great. Understanding that all passengers were tired with traveling and the flight delayed he did everything he could to get us to our destination quickly and safely. I could tell he was excellent at his profession. Kudos to all the flight staff!"
Cons: "I was most upset that a bottle of tequila I bought in the duty free store in the cancun airport was confiscated by tsa in Houston. I know this was not united's fault but perhaps my discontent can be forwarded to the proper people. I went through all the correct procedures to transport this via a connecting flight and through no fault of my own had it taken from me. It seems like sort of a scam that travelers are told they can purchase these items and legally transport them home only to have them not make it through security at the connecting airport. I was not the only one this happened to. Bad form!"

Pros: "the flight was very short"
Cons: "DID NOT like the way the boarding attendant treated me!!!"

Pros: "Thank You. Everything was great!"
Cons: "I feel bad for marking Food and Entertainment as poor; however, they were really both "not applicable". Please add another column. I'm sure the review will look much better :-)"

Pros: "This was a 4 hour flight. A TV would have been nice."

Pros: "United airlines reasonable rates And sevices"
Cons: "The delays was awful I'm disabled wasn't offered no assistant to get from one terminal to the next because your flight delays we waited 3hours to go from Chicago to Boston then get on plane and wasn't offered but a swallow of soda that was poured out of a twelve ounce can split between three customers And I'm diabetic my sugar was low because the unexpected delay So that made a perfectly good trip awful"

Pros: "Space was cramped, crew inattentive, coffee was undrinkable and tv would not turn off or play movies."
Cons: "See above. Will try to avoid United in the future."

Cons: "Our flight to San Francisco was canceled"

Pros: "Free direct TV was a bonus. We appreciated the extra space in the United plus seating (which does cost quite a bit extra)."
Cons: "Seats were very uncomfortable. Good choices were VERY limited in United Bistro. No good options for people that are sensitive to spicy foods."

Pros: "Flight was on time."
Cons: "Baggage was not assigned a carrousel. After asking where it will show up, I received a verbal carrousel assignment. Almost a hour after landing, no baggage showed up. We finally found it at the unclaimed baggage."

Cons: "In front of the exit row so weren't able to recline seats"

Pros: "The cabin and crew were very nice up in 1st class. The food and drinks were served on time and in a timely manner"
Cons: "Plane was delayed numerous times before it was allowed to take off. I ended up being late by 2 hours."

Pros: "Flight was on time, crew was great."
Cons: "The temperature was uncomfortable, air was hot, not cool. Thought the plane had a wifi sticker on the outside of the plane the plane didn't actually have wifi."

Pros: "Flight was on time."

Pros: "Even though the flight left 3 hrs late it was very nice...I still think you should offer free Wi-Fi. ..and it wss nice that the food and beverages were free because we where late..Thank you"

Pros: "Not overcrowded"
Cons: "Flight was delayed. No power outlets"

Cons: "This flight was cancelled and I was given no notification. I was only told once I got to the airport. Luckily the staff member I spoke with at checkin was helpful and put me on another airline, but only after she tried to tell me they'd sent an email and said there were no flights til the following day. I had to explain that I hadnt been notified, had taken off work, had just taken a cab there, was 2 hrs early, and due to the nature of my trip not able to leave the following day. Though she was very helpful I feel it was luck and the nature of using a small airport, not something I can expect. Either way I shouldn't have to explain and insist when it was clearly the airline's mistake. When I later checked my email I actually had never recieved a cancellation email, just an email saying cancellation was possible. Overall another bad experience with United. Flew American Airlines and was happy with the flight."

Pros: "Nothing"
Cons: "I have handicape son and they didnt give seat together"

Pros: "Reasonable amount of leg room. Much better that the flight out, during which all passengers were squashed in like sardines (and I'm a short, small-boned person). United should stick with this model plane and sell the other one for scrap."
Cons: "Complete and total lack of food on a 5+ hour flight."

Cons: "No food provided at all. Sound was painfully loud over speakers during safety video. No way to turn off TVs permanently - kept coming back on with advertisements. Did not have enough room for all carry-on bags on board. Was delayed and no notification given to passengers."

Pros: "Every thing"

Pros: "This was the first time my 19 month old had flown and it was a pleasant experience over all. I asked if the had a spot with an open seat next to it and they moved me so that he has more to wiggle."

Pros: "It's always great when the plane is not full and you have some extra room."
Cons: "I do wish that the plane companies would start to serve some type of food during a three hour flight."
