Airline reviews

Cons: "Unclear how Air Canada is still claiming “beat airline in North America.” I think that was true 5+ years ago but the last two years they have been an operational nightmare with customer service also being atrocious"

Pros: "I managed to get on an earlier flight with a standby ticket."
Cons: "First, my original flight got delayed to an arrival time that would’ve made me miss the last shuttle to my final destination. My options were either to stay overnight in Vancouver or hire a taxi. Both options would’ve cost me at least $300. Thankfully I had a longer layover in Toronto that gave me some buffer. Otherwise, it would’ve been an additional expense."

Pros: "We didn’t crash."
Cons: "We continue not to crash."

Pros: "compliance in the boarding"
Cons: "in general the male flight attendant was very disinterested in resolving nonconformities such as that the light of the chair did not turn on or request for support in completing Customs form and uncomfortable seat"

Pros: "Great staff!"
Cons: "Nothing"

Cons: "Terrible seating and washrooms."

Cons: "No more seats, rescheduled for the next day. poor service"

Pros: "Comfortable seats with entertainment screens for everyone and friendly staff."

Pros: "Generous leg room in coach class"
Cons: "Sat on the runway for almost an hour both to and from my destination"

Pros: "Flights left at the scheduled time"
Cons: "Planes are very uncomfortable. There is no entertainment in the cabin (tv, music)"

Pros: "Many airlines have code share flights but it is better to buy ticket directly from the original airline as they keep on ignoring the code share flight bookings"
Cons: "Till last moment we were kept hanging if we will board or not as no seat number was allocated. I believe it was as we were from the code share airline not the real one"

Cons: "delayed by 5 hours"

Cons: "Food was hilariously repulsive. Shared photos far and wide on social media."

Pros: "Overall not bad."
Cons: "Flight delay, tight seats."

Pros: "Not much. The entertainment choices were good, but other than that, things were mediocre at best."
Cons: "Boarding was disorganized. Seating was crammed. No priority was honored (being silver members who always get boarding on Zone 2, we were put in zone 4. The food was mediocre to poor, and beer or wine were not complimentary, even though this was an intercontinental trip."

Pros: "it got me to my destination."
Cons: "cramped for a tall person (6'3") such as myself. food was poor and portion small, bring your own. had to pay for beer and wine on transpacific flight."

Pros: "on time"

Cons: "flight got cancelled and was put on flight 1 hour later than originally planned."

Cons: "Delays"

Cons: "Gates changes a lot and no announcement is made"

Pros: "CAs are very kind."
Cons: "CA skipped me for snack Last years trip to Japan I experienced same they skipped me. So, I try to bring own snack next time."

Pros: "At least the entertainment systems worked this time."
Cons: "I've never thought that airplane food was bad before, but they ran out of the main options and I was left with macaroni and cheese. It was bad."

Pros: "Nothing"
Cons: "One of the Worst flights for punctuality 3.5 hours of delays ! Missed all my connections ! Over 24 hours in waiting ! Will try not to use air Canada again!!!"

Cons: "Delay getting to gate in Toronto. Entertainment system is not top notch. No blockbusters of any kind. Cheesy airline"

Pros: "Boarding on time"
Cons: "Problems with entertainment"

Cons: "Boarding Zones 3-5 is always a mess"

Pros: "No complaint"

Cons: "check in staff was unable to though tag me luggage onto an onward Emirates flight from Toronto. Not sure if this was a lack of knowledge or limitations of the check in system. Seat options provided at the time showed only middle seats as available all other sets were showing booked or required pay-up premiums...Air Canada's website had a whole host of end seats available...."

Pros: "Very friendly & helpful flight attendants."

Cons: "No food options, only beverages. Checked luggage is extra. It's a shame we're constantly losing services with flights but the costs remain the same."

Pros: "The crew tried to be nice."
Cons: "Boarding was completely disorganized. The flight was meant to depart at 3:30, we didn't start boarding until 4 and we didn't take off until 6. The flight was too full and the plane too heavy so extra fuel needed to get be left behind, which meant we had to land in Jamaica refuel and then head to Toronto. Arrival time was meant to Be 10:30pm and we arrived around 1:30am."

Pros: "Got home safe"
Cons: "Meal -"

Cons: "The lavatory sink was clogged. The audio to movies was inaudible, as though the picture was streaming and the audio was lost. The crew offered little assistance to a clearly frail elderly passenger who had a very difficult time rising from her seat and using the lavatory."

Pros: "Crew was friendly"
Cons: "No leg room, no snack for a 5+ hour flight, a bit messy, no entertainment, not too comfortable"

Pros: "We upgraded to premium economy which made the trip perfect. There was so much more room!"

Pros: "Excellent service on board, and excellent neighbor passengers"
Cons: "Being unable to check in on line and being assigned a middle seat."

Cons: "Food was mediocre Entertainment movies outdated"

Pros: "Good seats"
Cons: "Luggage was lost from Vancouver to Seattle with absolutely no communications and I had to chase it's whereabouts the next day"

Cons: "No breakfast offered for a four hour flight"

Cons: "No entertainment"

Cons: "We lost our connection by 20min because of waiting at customs were placed on the next available flight, bourded and them waited for over an hour inside the plane for a couple of customers that where stuck at customs."

Pros: "I really enjoyed the plane. It had comfortable seats and was very roomy. There was complimentary dinner and breakfast service, both of which were delicious."
Cons: "About 80% of my flight consisted of noisy Spanish high-school erst returning from some trip in Canada. They were loud and obnoxious and ruin the peace on the plane. This was an overnight flight and they ruined any chances of falling asleep. The problem came from the fact that the flight attendants could keep them under control. They, in turn, got annoyed and gave generally subpar and unpleasant service."

Cons: "I was not able to select the seat in advance although I purchased the ticket way in advance. We should be able to choose a seat online in advance. Especially when you are traveling with another family member a friend, you don't want be seated away from each other. That was one of the issues I had with Air Canada."

Pros: "Pleasant stewardess and crew"
Cons: "1 hour delayed flight was inconvenient for everyone"

Pros: "I really enjoyed my flight from food to comfort with blankets and pillows"
Cons: "TVs on flight didn't work on most Window seats sides and mostly worked in the middle. Wish they had checked the TVs before boarding everyone especially on a long flight."

Pros: "One of the stewardess is really cute and she speaks French"
Cons: "The cabinet temperature is ridiculously low and they only offer a thin blanket"

Pros: "The sits were comfortable. More space between sits."

Pros: "The flight was on time and the service was SUPERB!!!"

Cons: "Flight delayed for no good reason"

Pros: "All great in Biz. class."

Cons: "The WiFi for the personal entertainment system wasn’t working properly"

Pros: "United is fine."
Cons: "They have a Delay and they comunicated late. I traveled with a 3 month old baby, so you can imagine whe you have a delay of more than 5 hours."

Pros: "Made up time lost to bad weather. Several announcements from pilot-I always like that. Makes me feel more personally cared for. "My friend the pilot is taking me there". That might explain how it makes me feel. Wish they did it more. Don't usually complain but below you will see I did."
Cons: "Your headrest are especially cheap, plastic like, with little padding. Being in back row(no recline) would have been manageable if I could have leaned head to side to rest on something that extended out. Left too much light on (all down center) for an overnight flight. Served heavy dinner at 2am. Woke everyone up. Later light breakfast would have been more appropriate. Bathrooms reeked and waste bin overflow. Stewardess in back chatting. Don't they ever check?. They didn't seem to want to there."

Cons: "Worst flight experience of my entire life."

Cons: "Be on time!!"

Pros: "Crew was amazing seat are good from Denver to Cincinnati But from Edmonton to Denver seat were tight"

Pros: "The lounge and boarding area at Houston Airport were great. The staff at boarding did a good job keeping everyone happy and in line and boarding in the proper zones."
Cons: "All the flight attendants were trainees. I was served cold coffee because it took so long to get from the front of the plane to the back. I was given a toothpick to stir it with. My headrest detached from the seat, and I had to sit uncomfortably during the flight. The plug for headphones was broken."

Cons: "More room for your knees"

Pros: "I had economy plus so was comfortable. The check in and boarding was great, no complains there. Flight was before time both ways."
Cons: "For a 10.5 hour flight the food served was not enough. I am a 123 lb female and was hungry. I always carry snacks with me because of previous experiences like this. Also when you are at a window seat it is hard to get up frequently to even get water as the people next to you are sleeping. The stewardess came by twice offering only water. I remember before they offered juice and came around more often. They gave 1 small bottle of water after serving the meal. Wish that was a bigger bottle."

Pros: "Short and sweet no problem"
Cons: "Nothing"

Pros: "The crew was polite and caring. Always making sure I had what I needed. The organization for boarding was fast and smooth."
Cons: "The airline has to create a policy that control more the misbehavior of children on board. If children are not controlled properly, the environment becomes very disturbing."

Pros: "My bag made it onto my connecting flight in spite of the tight connection due to the delay."
Cons: "The gate attendant asked if I would be willing to move to a different aisle seat to allow a family to stay together. She told me it was the same seat, saying "aisle for an aisle." It wasn't--it was the worst seat in the house--last row, next to the toilet, smelled the entire flight, with no possibility to recline. I had booked my seat months in advance, so a concession offer, such as a food/drink voucher, or a seat in econ plus, would have been the right thing to do. Instead I felt like a tool. Makes me wary of doing something nice for the airline in the future. No plugs in regular economy class makes it hard to use the United app for entertainment. Also, kept getting bumped off the wifi app."

Pros: "Legroom"

Pros: "Short flight"
Cons: "Late departure due to late arrival of the plane from previous destination. Pushed our arrival time after midnight. Rental car agency was closed and had to rent from a different one at a very steep premium. No apologies and no assistance."

Pros: "Flying on the beauty Dreamlier Boeing 787"
Cons: "Luggage crew too slow in both airports"

Cons: "The flight was delayed by 3 hours and I recieved no notice at all. I had to buy a ticket for another flight with seconds to spare before they legally couldnt sell me a ticket. I almost missed my entire vacation. When i landed, i called to see if i could get a refund and i was told that my return flight had also been cancelled. Again, i was given no notice at all. This couldve resulted in me missing work. I will never fly united again."

Pros: "Help changes with my seat assignment"
Cons: "Leg room bad.....attendants. not very happy"

Pros: "Crew made sure we would make our connecting flight or had a backup flight if we missed the original."
Cons: "Running to barely catch my connecting flight. No ones fault"

Pros: "Friendly"
Cons: "Not good with disability wheelchair services sudden gaye changes unable to accomodate standy despite reprated attempts and multiple flight options with 4 hr airport layover"

Pros: "Short flight so not all questions applied"
Cons: "Too small seats"

Pros: "The crew and service was great!"
Cons: "The wifi was broken the whole flight and I was freezing"

Cons: "Multiple delays"

Pros: "One flight attendant who went above and beyond to compensate for the airline having prepared a vegetarian meal option"
Cons: "Called ahead to secure a vegetarian meal option for a 6-hr flight and the meal was promised. Once on flight it was explained to me that vegetarian option was not offered on this flight. If customer rep would have explained that, u would have taken measures to bring along a prepared meal for myself. Not okay."

Pros: "Entertainment was fine."
Cons: "Boarding process at lax lumped groups 3,4,5 together, guaranteeing chaos. No UA employees provided effective communication of process. Line was so long nobody could hear. Flight delayed as well, insufficient planning"

Pros: "Staff was great,trip was. Quick."
Cons: "Delays in take off"

Pros: "Economy tickets were over sold and I was moved to 1st class seat! Best flight ever.!!!"
Cons: "Customer service, baggage policy, service at the airport counter, in short everything."

Pros: "Really fast and efficient boarding"
Cons: "The flight was really bumpy which I realize isn't anyone's fault but I couldn't wait till we landed...also they announced that as soon as we were at a certain altitude they would begin beverage service....which I was really looking forward too , and then ten minutes later they announced that they were cancelling beverage service."

Pros: "Flight was delayed but the pilots got us there in time to make our connecting flight. Thank you!"
Cons: "On an international flight didn't expect to pay for movies and our seats didn't recline. Made for a long and uncomfortable flight."

Pros: "Because of the delay, I missed my connecting flight, but a United staff member was ready to hand me a boarding pass for a new flight right when I got off the plane. That took away any worry or hassle for me, which I appreciated."
Cons: "We sat on the runway for 2 hours. Also, my headphone jack was broken, so I could not connect my headphones to watch a movie. When I tried to explain the problem, the flight attendant misunderstood and just ended up bringing me a new pair of headphones... not helpful."

Pros: "Nothing"
Cons: "The plane was 3 hrs late from dulles to houston ww were only given snack they should given us a full lunch."

Pros: "Movies on plane"
Cons: "Over 2 hour delay caused necessity of connection to be unusable - no explanation. Virtually useless help in getting a new connection."

Pros: "The Embraer ERJ-170 has comfortable seats!"

Cons: "We were 3 hrs delayed getting out of RDU because a 'test button' wasn't working. Missed my original connecting flight and the two connecting flights they had me on standby for. got to ohare, the united customer 'service' rep said "there are no more flights to Madison today - I don't even have to look. If you want to get there today, you need to go get on the bus". They didn't even offer to pay for the bus ticket ! Just rude and no customer 'service' at all !"

Pros: "The crew was very friendly, fast with boarding and take off, and our flight landed early. Overall great flight"
Cons: "No complaints! Good job United."

Pros: "The crew was great"
Cons: "I was not able to use the TV because the key to change channels was broken. I did not like the food, Too many calories and starches and the airplane was old and outdated. Thanks"

Pros: "The crew was nice and the area was clean."
Cons: "I didn't like the fact that before boarding they offered to check peoples bags for free because so many people were trying to take ridiculous sized bags onto the plane. I always pay to check my bag . That process took for ever but we did still arrive on time."

Pros: "Getting on and off was easy."
Cons: "Small plane bathroom sink water didn't work."

Pros: "On time"
Cons: "The aircraft was a bit older for a 6 hours flight so I felt too closed to a person next to me"

Pros: "Short flight (51 minutes) and since we were late boarding, they made sure passengers with transfers were loaded first (this was so they didn't have to risk checking their bag but was not clearly communicated)"
Cons: "Flight before arrived late but this wasn't clearly communicated, just that we were delayed."

Pros: "Boarding on time, wi-Fi entertainment and staff were friendly"
Cons: "Nothing to suggest"

Pros: "Coming home"

Pros: "Everybody help me good information Thanks"

Pros: "I missed my flight and was willing to rework my schedule and therefore United was willing to work with me. I received a flight change for free because of recent terrorist events and I am grateful for the help. All of the staff was extremely friendly."
Cons: "It probably isn't United's fault, but since a terrorist attack occurred in France a lot of people were trying to fly back to the U.S. from Rome at the time. I missed my flight because the line just to get into the terminal building was hours long. See positive comments to learn how United handled it, but was still stressed I missed my flight home. I actually ended up flying home from Barcelona"

Cons: "Very difficult to get to EWR from Brooklyn and the departure was changed 6 times that afternoon."

Pros: "The overall punctually of the flight was very accurate and i appreciate that very much."
Cons: "One flight attended in particular was very rude. Blonde short and slightly over weight. Her deminer towards the passengers was very unprofessional. It is unfortunate to have someone like that in a 6 hour flight. Seats are very small and couldn't charge my phone. Also couldn't watch the flight path unless I paid for the entertainment"

Cons: "Was late like 7 hours"

Pros: "Punctual, good service"

Cons: "Tight seats - and I'm a small person!"
