I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

The crew was very good, excellent, they help me with my needs.! Food was not that good.

Everything was quite easy from boarding to landing - the staff was great and service was excellent too!

Flights are standard. But being over 3 hours late is too much.

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

Boarding was a shambles, with no proper line or queue and multiple groups joining at the same time. Overhead space was limited. Seat spacing (width) is not generous. My neighbour was invading my space, before he even spilt his drinks over me (twice!) as he struggled to contain his meal on the table. The main meal was very poor. Choice was simply chicken / turkey - the crew didn't know exactly which - or vegetarian. The chicken meal was really poor quality - uninspiring and tasteless; and very little offering of drinks. Half the crew were friendly, half really need to cheer up.

Food was pretty poor - bland, tasteless. Drinks offerings were very limited also.

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.

Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation would have been more acceptable, and it felt dehumanizing to him.

Needed a 6 hour lay over in Atlanta. How can this be avoided ?

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

Very good airline. There is still some room for improvement but overall I’m happy

The crew should demonstrate flexibility by moving a screaming infant to its own seat with 1 parent

The Virgin seats in business are quite narrow and also don’t recline enough in a seated position. When you make them into a bed, it is quite hard, despite the thin cover and cannot be adjusted at all, in comparison to business seats in other airlines. Virgin need to upgrade the quality of their seats. The food on this flight, I had an AVML was not good, normally though I have found the food to be good. Other than that, the staff were very attentive and pleasant during this long 14 hour flight.

One of the best flying experiences I’ve ever had.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Unfortunately this is not a happy ending comment. Positive: flown United before no issue Negative: it only takes one bad experience to not plan future travel with United Cancún departure was delayed by 1h20 minutes, connection in Chicago was 1h30 minutes. Flight departure time 6:08 Miraculously 7 of us ran 4 kilometres through Chicago to arrive at 6:00 to be told very rudely by the 2 unprofessional United attendants you missed your flight and that we should of arrived early. Did I mention that reason I was flying? I received a call that my brother was dying and to get home. They provided no assistance would not answer any of our questions, ignorantly walked away. Deplorable

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

This flight was a code share on Air New Zealand.

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Boarding process was well organized and orderly even though flight was fairly full. Water bottles were provided during boarding which was great as I drink a lot of water. Bathroom was not as clean as it could have been but was acceptable and fairly dry. Food however was mediocre. I have had better food on 2 hour local flights in other countries.

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

The overall ambiance was good. Seating ain the last row not so pleasant.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

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

Excellent service by united air staff. Very helpful, understanding and do friendly.

+ Clean, modern plane. - Despite the cabin had only 50% occupancy I was cramped in a row with 2 other people. Almost all other rows had only 1 person. I would have expected the airline to offer assistance other than a flight attendant to tell people in the back of the plane to find available seats. Next time I will not purchase an upgraded seat and hope I get my personal row for free.

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

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

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

Flight cancelled and i was rebooked on delta. Delta business class is not the same as British

Boarding could be smoother. But the flight crew was excellence. Very professional, friendly and helpful.

Everything was fine except my screen wasn’t working and I was unable to watch any movies or TV. Staff tried 3 times to reboot it, without success.
