Yves-LeoFlew with British AirwaysNov 2024
allow plenty of time for security check. Take all liquids, cream, make- up, foundation etc. out of your carryon luggage. a lot of travelers had their luggage pulled over for open bag check. This slowed down the screaming process considerably and caused me to lose my flight.

Basic service for the basic price. Efficient and cost effective, so ticked all the right boxes.

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

To complex. So many types of fare. This made the boarding a caos.

Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

I had a mixed experience on this flight. The plane itself was comfortable, the flight was smooth, and the entertainment selection was excellent with plenty of movie options. However, the service fell short. I had an entire row to myself and fell asleep with a blanket over me. A flight attendant, Karleigh, woke me up to see if I had my seatbelt on, which felt unnecessary given the situation. Meanwhile, trash sat uncollected on the tray at the end of the row and was never picked up. During the second meal service, no one woke me up, and when I used the call button multiple times, there was no response. I eventually had to walk to the back to ask for assistance. There was also a long stretch without snacks, and when I requested something savory, I was dropped off sweet options, which wasn’t ideal. Overall, while the flight itself was comfortable, the lack of attentiveness and responsiveness from the crew made the experience disappointing.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

British Airays fails to enforce its own guidelines regarding carry on size limits. There were MANY passengers with full suitcases stuffing them into the overhead compartments leaving no space for others, like me, who adhere to the posted sizes. I had to put my carryone bag into my foot space, in additon to my carryon personal item, leaving me cramped for a seven hour flight. I was in physical pain, and I attribute this entirely to staff unwilling to enforce limits. The infotainment system was horrible. the touchscreens did dot work correctly, and there was no information on system operation. I am 77 years old, and a lifelong movie-goer. I recognized ONE movie (and not much better TV shows). It seems that BA saves royalty money by limiting its move and TV selection to absolute rubbish. The FlightAware program is the worst informationsystm I have ever seen, it is completely worthless. I pay attention to the safety briefings...in the event of an emergency, one is supposed to assume the "brace" position, except the seats are so close together, front to back, that it is not possible to assume the position without striking the seat in front of you. at age 77, and a lifelong traveler, this is the worst flight experience I have ever had, and I will never fly British Airways again

Overall ok. Best part has always been the sundae dessert.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Was upgraded to business class on this flight, I presume due to my premium economy class for my London to Denver flight. Business class was the same seats as economy, only the middle seat was unfilled. Decent lunch served, and the lounge experience in Prague was good. The only heads up I would give is give yourself enough time for gate carry-on luggage scanning, which I did not anticipate in my time planning.
