No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff were fantastic friendly nice they came round and check we need anything else to eat or drink

From the start everything was perfectly fine. First meeting was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

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

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

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.

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

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

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.

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

The line at boarding was not well organized and managed

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

Textbook great flight. On-time departure and arrival, clean plane, good food, friendly flight attendants. Checked baggage delivered promptly.

Liked Seat space in Premium Plus Disliked delay, poor management of boarding groups, missed meal at landing.

The male air hostess was rude and didn’t even offer me a drink. Poor customer service!

We left really late. Things that were out if anybody’s control I guess.

When I purchased my ticket, I assumed it was a real ticket, as in, when I go to the airport I am guaranteed a seat. Not so. When I checked in 24 hours ahead of time, I noticed I did not have a seat assignment and my boarding pass said "Standby." I was informed at the gate that the flight was full and I may not get on that plane. I don't recall being offered the option of selecting a seat when I checked in, and apparently, for the honor of pre-selecting a seat, you must pay an additional fee. So, a ticket really isn't a ticket, it's actually a lottery and if you're lucky, you may make it on board - or you can choose to be extorted for extra money for the guarantee of a seat. It's like making reservations with the Godfather - one payment isn't enough, there's always another bribe you have to make. After the first few zones were called and I hadn't been informed of my status, I went to the gate agent and they handed me a boarding pass, for the very last row near the restrooms, in between two very large people. Apparently that was my punishment for not purchasing a seat ahead of time. Airline service has not only gotten more expensive, but the return on your money has shrunk and there is little regard for the passengers. This feels like a racket. I am not pleased, as you may have gathered.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Not much food available, not able to choose seats to be near each other, tv did not work

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

Catering strike impacted food service. Snacks & water were available. Gate staff did advise "if you want food on the plane you will need to bring it aboard". Entertainment system not available on this flight. Boarding was early. Departure was early & arrival was early.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

Delays upon delays. Food was gross. Separated me and my spouse is the seating I heard others complaining they weren't sat with their loved ones either.

Cabin crew were great. Seats are criminal for tall people

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Overall great flight experience- on time, lots of food and movies.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

bad seats, meager food quantity. bread not fresh. Hollywood films lack entertainment.

Great flight. Left on time, not very crowded. Quiet and the right temperature.
