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

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.

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

Business class in the second leg - CDG-EVN was a disaster.

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

No bording was given for next trip on same carrier, food was very moderate.

No birding was given for next trip on same carrier, food was very moderate.

Sky priority means you get to use the KLM business Lounge.

Je n'ai pas pû incliner mon siège et une des hôtesses ne comprenait pas ce que je disais. Je devais parler fort

Delayed flights. Missed connections. Inadequate rebooking timeframes. Incompetent customer service agents. Rather than a 70 minute flight home, I had to drive for 5 hours, arriving home at 4am — epically bad experience with United that I won’t soon forget.

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

My luggage didn't make my transfer in Newark. It took 4 days to receive it even though I tried to pick it up at the airpory

The food needs to be improved, up to the standard of the people and the accommodation.

We have taken this flight before and it is a tight connection and they were late out of denver and did not wait for us. The plane was there and the departure time had not passed but would not let us on. Next flight is very late and a connection through Newark - a big mess. Sooooo appreciate them holding the plane so we could catch the connection.

I had a great flight experience on United Airlines. This was my first time flying on United and i have nothing negative to say. As a person with a visual disability, I received reasonable accommodations. The flight crew was friendly and attentive in helping me and communicating safety protocols. I really appreciate that they came to speak with me. I felt safe and comfortable flying on United. I also liked their snacks! They taste much better than the snacks offered by other airlines.

The crew was not friendly . Service was poor. Food was not great. It was also an older plane that ha some equipment issue.

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

Pulled out of the gate only to sit in the tarmac for an hour and a half for paperwork. Paperwork. Went back to the gate to refuel.

This plane is my favorite despite the very limited overhead space. Seats are comfortable!

Not sure about entertainment as I didn't use any, so maybe there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

It’s never made crystal clear if your flight will have in flight entertainment or not. That should be explicit

The flight attendants were rude. People sitting next to me agreed as well. Wifi wasn't to bad... it went into and out a few times.

The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.

Iberia didn’t let me check in online or select my seats, the experience overall was not very pleasant

Late arrival flight arrived in BWI and I missed connecting flight in CLT to mobile. I had to wait 6.5 hours for next flight.

Our flight was delayed 45 minutes and we missed our connection, while we were able to get a flight the following day the voucher for food did not work.

Gate lady was short & annoyed with us when we had already missed our connection to Albuquerque. She finally gave us both center seats. American Airlines is my least favorite airlines.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Treating guests with respect when they are having issues. Myself and another guest were expected to climb over someone who had a disability and was clearly not well. There was no assistance. Also when the lady beside me asked to see if there was a possibility to get off the plane as soon as they were able because her husband is having emergency surgery the flight attendant’s response was so rude and dismissive.

There is no reason for a 5 hour flight, the only option is purchased food and free drinks. The airline should at least offer free chips, peanut, etc and then the option to purchase additional food

I like the tv show the seat was ok and the crew was awesome

Nanaimo to Vancouver was fine but flight from Vancouver to SFO was not so hood. Major problem besides 7 hours of weather delay was the fact they let 4 very drunk men on the plane into first class. They were awful! They should never have been allowed on.

Alright. 15 hours is too long of a flight. I wish the connection was out of Vancouver like it was on the first galf

We mist are connection do to a mist count we left 1 hour late so we had to rebook a flight and because of the mist count all are activity we’re all mist

It was a very pleasant trip from A to Z.

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.

Every leg of my trip with Air Canada was delayed Never offered as much as a small bag of pretzels on. 3 hour trip Printing boarding passes at the airport when told to bring printed boarding passes with you Unable to load passes into my apple wallet- so very easy with other airlines
