My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

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.

The design of the light switch on the arm rest is ridiculous.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

Boarding was easy. RDU gates can get crowded, be prepared to be patient. Flight was smooth, with excellent service. Pilots really provided a lot of visibility into flight details. Plane and seats were clean and serviceable. TY!

Cabin crew was very friendly, requests were satisfied promptly and cheerfully, and the cabin was reasonably clean when I boarded. The United lounges at Newark and Heathrow are always well-run and comfortable, especially Newark. I look forward to the new lounge that will be part of the rebuild of Terminal 2 at Heathrow.

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Free wifi was available, but only some time, being at least 30 minutes into the flight. it would have been better that an announcement had been made about the delay.

Good crew and a great experience. Only good things to say.

Great thanks - a whole row to myself. Good food but film selection not great.

Packed commercial flight was as comfortable as can be expected

It is okay. Flight was on time to start and early to land

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.

Boarding was a shambles, pushed us all onto the airbridge and then made us wait for ages

Spacious business class lie flat sear. 2 hour delay leaving LHR led to a misconnection in Phoenix. I was place on a much later flight but that would mean a 6 hour lay over - more than half the time it took to fly the 5000+ plus miles from London, That second flight was only an hour! The staff in London said they could do nothing which led to uncertainty through the long haul flight. Thr agents in Phoenix were very responsive put me on a 5 PM flight to SAN but that flight was delayed so we took off around 6. There is little storage for personal items in the pod. There was no vegetarian meals left so flight attnedant did her best to cobble a meal from snacks. All in all I was disappointed in the AA experience.

Very good. Flight on time. Cabin crew were all really friendly.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

Boarded smoothly, took off on time. Entertainment screens were reliable and the movie library is abundant. Food better than wtst was served on the first leg of the journey by another airline.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Check in was incredibly fast, fukuoka was comfortable and crew very pleasant. The only negative was that the boarding was somewhat chaotic, but it so often is these days as airlines tend to board by how much you pay and not by what an orderly process of filling the plane would be.

It was ok. Even after the airport bus took us to the terminal , we did not expect to walk 35 mins inside the airport to the gate . A 15 min walk is ok . Especially if there was any delay in TSA check which happens to is too then people can easily miss the flight.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Very disappointed with how we left Heathrow, and the service from Air Canada. When food was given, I was skipped by the attendant, and when I went to tell him, he just dropped the tray of food on my table. Leaving Heathrow and landing in Montreal were bad, which is not Air Canada’s fault, but the service itself was not good.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

A snack would have been nice instead of having to buy food.

When i booked my flight, my ticket shows that i have 2 pieces of luggage allowance. Once i got into the check in, i was informed that i needed to pay extra for my two suitcases, and was put into a very precarious situation, I had to pay close to £200 for my two suitcases and these were not extra burgages, I felt extremely disappointed. In case i never had the kind of money, it meant that i would have missed my flight

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The airplane was old. Some things didn’t work out of middle seat was broken. The rest was OK.

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.

Very quick boarding. I was surprised we only got a small water and small thing of cookies, everything else was for purchase. No entertainment. Crew was excellent though.

Flight delayed in terms of boarding and Kayak was great in updating but the team on the groping at British Airways were really poor

A basic tea/ coffee and a snack could be provided especially for long distance flyers.
