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.

Typical flying experience in the US. Nothing particularly good or bad.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

This was a code share Latam Airlines flight - everything very good except there was no seatback entertainment

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

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.

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.

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

They lost my lauggage and I STILL HAVE NOT RECEIVED IT. NO ONE IS HELPING! PLEASE HELP FIND MY LOST LAUGGAGE

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.

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.

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

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

There was no air on the plane and it was very hot.

Preferred the UA flight compared to the Air India. The seats were more comfortable and the food was good enough.

The width of the chair is very small. Not comfortable at all.

We flew SEA -Houston-Panama-GYE round trip. The connections were torturing because we had to sleep over in Seattle to board the early morning flight and froze for 11 hours in Hoston for the return flight to SEA. Not United's problem, just the inconvenience of numerous transits. Restaurants and fast foods were closed and all we got was a cookie/coffee for each flight. Finally we waited for a long time for our baggage at carousel 9 as informed by the APP and all reliable sources. Suddenly some fellow passengers found out that our bags showed up on carousal 8.

The incoming flight was delayed so boarding didn’t happen on time. Upon landing in Munich, we couldn't pull up to a gate so we had to disembark on the tarmac and be bussed to the main terminal. This caused a mad rush for me and others who were making connecting flights to get to our new gates, and my bag didn’t get over to the new plane in time.

service was slow and at times there was no service at all in premium plus seats. they do not care about people in premium plus

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.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Very poor the plane itself was really old, slight smell that couldn’t be named. I didn’t even get a boarding pass UNTIL AFTER clearing security! Even then, they said when I get to my connected flight I’ll get my 2nd boarding pass there! A bit ridiculous!

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

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

Very good. But seat selection was not good. We were put on different rows. Would have been nicer to sit besides each other as a couple.

Wheelchair help is not reliable & chaotic. No food and minimal liquids for a flight at 6;25.

Boarding was very orderly. People should be made aware of what food is being offered when booking is made

I have not flown a major airline in over 10 years. All 3 flight with Rouge were late leaving and arriving due to various issues. I was worried my suitcase would get lost because I checked it 3 hours prior to flight. The flight was over an hour boarding and leaving and they lost my suitcase in Montreal. Lined up for over an hour at YVR for baggage location and the line never moved. Had to phone it in and that took forever. I should have been gome by 1am and was not back until 5am. I had been up 23 hours. Bag was not delivered until two days later. Could not hear a word the stewardesses said over the engine noise. At Jean Lesage 2 Rouge flights were cancelled, 2 delayed, and 2 on time: not good stats. Terrible experience. Oh yes, and in the case lost were my mother's ashes. She passed in May and I was unable to attend her funeral as I have a disbled 22 year old who cannot fly. I was in Quebec to meet my birth family for the first time at my grandmother's 100th birthday. I spoke with and wrote my mother for the last 8 years. We have never met. It would have made a damning story for Air Canada on the news if that bag had not been found and returned.

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

Crew was good. The plane was a Time Machine from the 80s. Entertainment was constantly lagging and looked like it was running on Microsoft 99 operating system. Seats were uncomfortable. Only food offered was pretzels for a flight running from 14:00-19:15 local Toronto time. Second time I’ve flown Air Canada and I will avoid it in the future as much as possible.

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

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