I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

United ground crew and pilots are friendly. The in-flight staff (flight attendants) are the worst in the world. Multiple trips, always unpleasant, combative, use implicit threats to not allow for a discussion on their decision. Authoritarian. This seems to stem from an internal corporate wide policy as I doubt that United is intentionally searching for people that are not fit for customer facing positions. I will not fly United again. Good luck fixing your business

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Great - quick boarding and landed early with an available gate.

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

3 hour delay on run way, not even a drink offered, staff seemed rude and rushed, felt unwell so asked twice for paracetamol and was told to wait, never got it

On time, smooth, luggage was out fast at the end of the flight. About perfect.

Flight departed on time and arrived a bit early. Can’t go wrong with that! And makes a travel experience go so well

WiFi wasn’t working on the flight, several delays and gate changes, ended up taking off 3 hrs later

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

Overall the new aircraft’s is good and crew is good. Just overall airline policies and process needs to be better.

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.

Air canada always does an excellent job with business class friendly staff great food ......

Ordered the vegetarian meal. Perhaps the worst in flight meal i ever had. Soggy and sad broccoli, overcooked rice and a FROZEN cheap fruit salad.

The seats were very uncomfortable. The food was terrible. They only came around with the drink cart for dinner and breakfast. What if we needed water or something? I had to take my pills in the morning with a pop I bought from the airport. Absolutely ridiculous! Will never be flying Air Canada again after this trip!

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰

The walk from landing in Toronto to the flight to Winnipeg took us nearly 45 minutes. There should have been some type of transport available.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

I will travel by BA only in future also. Only suggestion is they should give aisle seat in front near washroom for senior citizens

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

Comfortable, pleasant staff, quiet, good entertainment, food, drinks. Better than American (flight back) when we were crammed in and staff sometimes indifferent.

Pretty disappointing. Paid for business class. It was burning up the entire flight. For a 7 hr flight, after the first few hrs. The crew disappeared. Poor service.

One frustration after another. No gate personnel until very close to departure. Boarding procedure was chaos. Plane was dirty from previous transatlantic flight. Entertainment system not operational. Gate change for connecting flight which required another round of security clearance, almost causing a missed flight. The final blow was lost baggage upon arrival.

CVG to London was a good flight . Thank god the plane was not full . Seating was tighter than any international I’ve taken . We arrived in London 10 minutes early. Had it not been for handicap assistance I would have missed my connection. Had it not been for the extra 10 minutes because we landed early I would have missed my flight . 3 hours and 10 minutes from plane to plane as they were boarding when I arrived . None of that is the fault of British Air but the understaffed and confided security at LHR. Because of this I will never use British Air again unless I don’t land in London . Not the airlines fault but I never want to miss a flight because of the blunder in London . The worst I’ve ever encountered in international travel . Sorry British Air but your home needs better management.

Food made us sick for the rest of the day. Terrible passenger in front of me kept reclining and banging his seat, it hurt my knee multiple times. I kindly asked the attendant to intervene, she would not. Way too many sick people coughing on the flight without wearing a mask. Sick passengers should not be allowed to fly unless they wear a mask. I hope we don't get sick for our 2 week vacation

We didn’t flight with British Airways because the flight was cancelled at the last minute .
