It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

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.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

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

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

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.

Better seating for sure. The seats were so close together for such long flights.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

No issues other than paying twice for my seat selection.

Always good Thought the seatings were a bit tight for food. Made a mess with salad and oil.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Very crowded; wanted us to check in 1 & only carry on full of meds & supplies; crew very reluctant to approve! I’ve lost checked in luggage in past.. It was non negotiable in my mind!

All was good with comfort and ease of boarding. There was confusion from what gate to board at. Meant moving a long distance but I allowed plenty of time for this.

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.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

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…

eveythink, because of you I lost 100 euros for my train connection
