Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Good and consistent Printer in lounge did not work for me :(

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Everything was Okay. I was disappointed our luggage didn’t arrive with us and came in a flight 7 hours later. Representative said the will be delivered to the hotel. They have not arrived 24 hours later

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

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.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Very good crew. Food service above average. Seats very small for a 12 hours flight.

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Extremely poor. First - and oddly enough, Air France denied access to the Business Class lounge at CDG to all of us - although we were all flying Business Class. It is amazing that an airline denies lounge access to its passengers flying on business and paying several thousand dollars each ticket. Second, the food on Business Class on absolutely horrible. Air France must have made an effort to prepare bad tasting dishes (not even the ice cream was good). Third, the cabin temperature was too hot and although we complained many times, it never got cooler.

A disaster. Air France is a real joke. They overcharge us customers for absolutely nothing. Service was very poor, food was mediocre, entertainment non existent, etc. We paid thousands of dollars for our business class tickets and then we were told in Paris we could not access its lounge. Really Air France ? Congratulations on irritating your customers to the sky high level and ensuring we will do everything in our power to discourage others to travel with you.

They again did not offer any functioning WiFi in the transatlantic crossing.

The first half from DC to Paris was very good and the staff were very helpful and humble BUT flight from Paris to Mumbai was sad. 1) it was packed. 2) no space on head compartment 3) crews were unresponsive to the calls 4) one crew member literally banged the bottle of water after giving me glass of water. A little water splashed on me and she was unapologetic 5) with so many hours of flight, little leg space should be taken care else don’t fill your airline till brim which affects your crew and they remove anger on us. 6) huge line for washrooms. 7) 2nd half journey was pathetic

At check-in at Guarulhos Airport, I was coerced to pay EUROS 100 for each of my two teenage kids travelling on economy premium on the same flight (total charge of EUROS 200) to AIR FRANCE on the rational that they were on a different class and therefore they would require additional care from the flight crew. My wife and I would be (and actually flew) only a few meters from our kids on business class in the same flight. Air France took EUROS 200 from me in exchange for absolutely nothing. My kids are seasoned travelers and independent, and in any event, they were not given any special or any other assistance or attention by Air France flight crew as result or in connection with the fee charged from me at any given time during the flight to Paris - so ABSOLUTELY NO SERVICE WAS PERFORMED AND THE FEE WAS SIMPLY ANOTHER WAY OF “MILKING “ EXTRA EUROS 200 FROM ME. Worse, Air France made us wait for everyone to deplane in Paris to let us deplane - after an Air France Paris representative ridiculously confirmed that our kids were our kids, with our kids at that time already by our side seating in business class. We almost lost our connection to Malta as a result. Such a scheme from Air France is outrageous – especially because it penalizes its customers flying in business class or in first class. I would have imagined that Air France would have wanted to attract clients to fly its premium classes – not to charge cheap EURO 100 fees and to keep them waiting to deplane with their families after 12 hours flights at their destination. You won’t see us any time soon Air France and best of luck with your strategy !

horrible website for checking in- no option just to write the passport number; ludicrous

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

We were delayed because of ground crew, not because the plane wasn’t ready to go. The food was better than usual!

Boarding in Paris was a nightmare for us. Why passengers have to get checked luggage tickets and then to go to counter to get luggage weight and send to the conveyor? We counted 14 security and airline checks before getting in the plane. We will never again use United or travel to France, neither stop by IAD airport.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

Great crew, boarding and deboarding excellent. Seats too close together. The 5'8" woman seated next to me had her knees pushed into the seat in front of her. The meat was very tough in the dinner...

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

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Exceptional, I’d like to specifically recognize Robert for his outstanding customer service. He is professional, pleasant, and personable.

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…

Liked having internet over the ocean. Arriving meal was not sufficient.

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

We didn't get any food, not even a snack. Besides of that the experience of flying with Air Canada was great

United agent at FLL excellent - due 55 min conx at ORD rerouted us on an earlier departure via DEN and got home 5 hours earlier than expected

Good for me, bad for you. I had the whole row to myself because no one wanted to pay extra. The flight crew were very professional and tended to everyone’s needs. Definitely flying again.

Older plane, business class was not up to par, entertainment screen small and dim and average food.

My wife and I did not find the flight crew to be very friendly. They just need to be more polite. The meals were not very good. They served chicken with soy sauce on a flight from Madrid to Toronto. This was not a flight to or from Asia. Our flight on September to Madrid had much better food.

Easy boarding, punctuality, decent service. I can only complain about the measly snack.

Our flight was delayed 6 hours and we finally got to Montreal at 9PM, instead of Houston where we were supposed to be. Several flights we could of got on and fixed our situation were nixed as they wouldn’t put us on a plane w/o our bags, but when they finally canceled our original plan they easily located and relabeled our bags. No one seemed to care.
