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

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

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.

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

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.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

More up to date movies and a live TV option like ESPN, Fox News or CNN. All they had were movies and Spotify Music and some games. Also, wifi on international flights isn't free for Skymiles members like on domestic flights via T-Mobile.

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.

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.

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

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.

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

Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional

Every single flight with them either cancel or delay for stupid shift. They are full of excuses.

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.

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.

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

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.

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.

I was randomly deplaned in Canada for staff's fault. Terrible experience and caused me a lot of delays.

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.

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.
