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 .

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 .

They charge me for luggage which is was included on the ticket

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

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

Lost luggage, 2 bags were badly damaged and one of the bags came open.

The line at boarding was not well organized and managed

The crew was great and handled our unexpected detour with proactive communication.

Even though my seat is a paid seat, I was told to give up my seat to a passenger. I tried to ask the CA to negotiate, and when I spoke in Japanese, the CA fled. I had to find a Japanese CA and ask them to deal with it. . After takeoff, I spilled my coffee, and when I asked the flight attendant for a towel, she told me to wipe it off with a wet tissue. My clothes got wet, so I asked CA for an extra blanket, but I had to wait for an hour.

Please serve no god if you must serve dog food

Flight was more then 3 hour late and I did not get my luggages

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Excellent as always. Had issues checking-in online. Please fix.

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

It was fine. Everything ran on time, crew was great.

Staff friendly and app worked really well. Modest delays were frustrating

This flight is always a cramped bus. The gate area was inadequate and announcements were hard to hear. The flight was delayed 45 minutes to an hour by a broken aircraft door, making our total delay from Vilnius 5 hours.

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.

I wrote about this leg of my itinerary in a previous part of this review

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

Crew was rowdy and loud just hanging out in the rear of the plane instead of assisting passengers during boarding. During the flight the crew mostly hung out in the rear of the plane being obnoxious to a point of disturbance.

United flight from Frankfurt to Istanbul is on Lufthanza and United could neither provide a boarding pass or Lufthanza code to get a boarding pass. Very poor connection ability in Frankfurt and much frustration with the connection.

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Good with last minute upgrade Clt to Munich comfortable. Wish same offer had been there Mumbai to Munich

The crew on this flight were excellent. They were friendly and attentive. It really made the flight more enjoyable.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports

American was good / British Airways partner was not as good…

The entertainment system in our row was not working. That makes for a VERY long flight!!

A little more legroom, and maybe a little bit of food

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again
