The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

The experience was good and the flight departed on time and landed early

I didn’t not like that I could not select my seat and ended up with the worse seat.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Delay at gate caused a flight change for our connection, hotel stay, and lots of standing and waiting in lines which hurt my feet and was unpleasant as people were grumpy and yelling. Delta worker Nestor Espinosa was very helpful! Others were apathetic (tired I’m sure!) but weren’t clear with instructions and didn’t give both of me and my travel partner the same food voucher etc.

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 !

Forty five minutes late for departure. Staff were pleasant. Food was adequate but not outstanding. Entertainment system was very good, as it usually is on Air France.

My only issue was my meal was inedible except for the sides.

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Generally good. The crew is excellent. The food could be better.

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

Food could have been better especially the breakfast. Overall it was a good flight

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

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

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

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

Lufthansa placed a 300 lb passenger in the aisle seat and I was stuck in the middle leaning sideways with no arm rest or ability to sit up straight and fully use my seat (due to encroachment-the seats are very narrow) the entire flight.

My flight was delayed for a whole day, so I lost a day of my vacation.

45 minutes delay and not clear way. Almost missed my trans-Atlantic connection

How would you rate my experience when I was stuck in YOW without being offered a cup of water by the airline?

The lady at the check in counter wasn't helpful

Two staff were rude, loud and burnt out I think. Two were friendly kind and helpful.

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

Could not switch flights. No help from check in Four people doing nothing. Two hour wait on telephone but no other flights available. Overall experience sucked.

Everything was excellent. Just keep doing what you are. I would travel with this airlines gain.

Flight was delayed more than 120 min. I had carry on bag but the airplane was full and they had to get it checked in. I had to wait for the small carry on bag at the airport carousel

Flight was good. Really appreciate the second hot food offering. C

The plane was new. Should give more options on food.

Delayed 2 hours 20 minutes. Then we still didn’t take off for another 45 minutes. Arrived in Toronto and no gate was ready for us so we were stuck on the tarmac for another hour. Missed my prebooked Uber and had to pay the cancelation fee plus book another one. Got home over 5 hours later than planned. Awful planning.

No food other than a tiny snack. The flight is too long for not having a more substantial food option, other than buying the overprices and mostly non-plant-based options from the menu.

The chairs were too upright, but not awful. Boarding was fast and efficient and we did not sit too long in the plane before takeoff.

We had a 13 hour delay over at Montreal and our luggage was never delivered

Air Canada cancelled our flight from Paris to Montreal with less than 24 hours notice, completely ruining our plans for the last day of our trip. Their associate tried to help by rebooking, but there was only one option available from Paris that was impossible for us to get on. There was no compensation for the disruption, and in fact, we had to pay an additional surcharge after losing money from another flight we had to cancel in order to accommodate the change. Before arriving in Paris, our flights were changed 5 times, but we had more flexibility while still on home soil, so the changes were manageable. Very unpredictable company and poor customer service.
