Extremely poor at handling baggage. I had oversized golf bag and JAL would not recheck in Boston. Had to haul by myself to Jet Blue. Both JAL and Jet Blue claimed I had overweight bag. Had to adjust baggage several times. Will avoid JAL in future and I always avoid Jet Blue when I can. QATAR always superior.

Extremely poor at handling baggage. I had oversized golf bag and JAL would not recheck in Boston. Had to haul by myself to Jet Blue. Both JAL and Jet Blue claimed I had overweight bag. Had to adjust baggage several times. Will avoid JAL in future and I always avoid Jet Blue when I can. QATAR always superior.

I fly to Asia twice a year for the last 15 years. I always try to fly JAL. It’s always a pleasant experience. Since TripCase shut down, this is the first time I used Kayak for live trip notifications. I was very pleased with Kayak’s quality and helpfulness of notifications. I will be using them going forward.

First experience with JAL so was okay to pretty good. 10 hour flight in premium select seat. . Seats in that category should be better than pretty good. Seat pan a little short for tall people but plenty of leg room; I think JAL in process of new planes? Also, — they could have offered a bit more water throughout flight and meals not the greatest. That said, certainly 200 percent better than a very recent AK Air International flight in similar cabin class in comfort and meals.

We ordered for non vegetarian Hindu meal but instead they served us vegetarian Hindu meal. That was also not good. It was very annoying and aggravating. Hope our return from Tokyo to jfk on March 27 same is not repeated. Caterar should understand difference between non vegetarian Hindu meal and vegetarian Hindu meal.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

The team members are extremely attentive to make sure you have the best experience.

Was in premium economy. It is slightly better than economy, but the way the seat reclines actually makes it harder to sit (the seat slides forward and the foot rest comes up - you can lie fairly well reclined but you’ll have to sit cross legged because there is no place for your legs to stretch out. Food is basic economy. Service was great. All in all good, but may make more sense to pay more for business or save a bit and just sit in economy.

Seats in "Premium Economy" were noticeably more comfortable than those in "Economy" and worth the price. My only reservation is that the foot rest did not go higher up. If it did, it would have made the seat much more comfortable.

A great flight experience - great seats, lots of ROOM for legs & in the aisle. Great attendants! My flight cost me the same as ZipAir, the website was WAY less confusing & wonky - this will be my 1st choice for my next Japan trip. Very pleased / well cared for.

Underpricer was terrible. They wanted to charge me $150 for a seat asignment. Kayak is responsible for letting this happen. Please let me know if this is going to happen in the future. If it is i will not use kayak in the future.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

Pitch was very small. Knees were on the seat back in front of me.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

All was good except for the seats, not very comfy.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

This flight didn't happen for me because of overbooking.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.
