Our previous flight was delayed but they waited for us to board.

Arriving at Heathrow was a complete disaster because air bridge broke down and it took ages to find spare stairs! Something that I'd kick Heathrow in the shins for, not Finnair - who were great.

All good- I love BA and the professionalism of the crew and pilots.

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Had a nice flight to London on BA will fly with them again in the future

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.

Very rude hostess. She embarrassed me in front of others. I went to sit after taking off in a different sit in the same economic cabin. Was the area where doors are. She come to me very laud and said: go back to your sit those sit are more expensive.wow! No diplomacy. Flight was super full except 3 of those sit. The only person in that row later during the flight occupied all sit laying down!. Once more disappointed at American Airlines. Early flight they lost my luggages for 4 days. Never refund money for replacement for some of essential items purchased..when I booked the flight I thought was Finlandair. I

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

Excellent service and always our preferred choice of airline. Was surprised we had to pay for soft drinks though. Other wise great airline and customer service!

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

Great crew - old style upper class seats on the older fleet now feels dated

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

Seats were very comfortable and the staff too was very friendly.

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

Should have had business class line in immigration. Food quality suboptimal

In my opinion, Etihad Airways is a first rate airline except for one important element. On the day before my return flights, when I chose my seats on the Etihad website I was charged an additional $55 (US) in order to sit on the aisle. I was not at all happy about this additional "hidden" charge and I felt cheated.

Good leg room and I picked the seat in last 24 hours. Food was tasty with 2 full meals and first one smaller. The crew as expected courteous and on their toes serving extra water and items in between.

Nothing was good everthing was hopeless especially your staff at indira gandhi international airport india.Everthing has deteoriated

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

I Keep your expectations to low to middling with BA, or most European/ US airlines these days.

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.

Very bad because flight was cancelled and they never informed me i have to wait for three days in hotel to get another flight

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

Biz class has a middle seat. 🙄. WiFi only for first class. No free seat assignments. Basically nickel and dime approach. They need to take lessons from Singapore Air and the likes. Never again.

I have not used food or entertainment all other services I used were simply excellent. BA crew is always good in service. The BA Crew at anygiven flight is simply amazing.

The behaviour of Cabin Crew was really bad and they didn't serve food in my 10hrs flight even though I booked my flight food . They didn't treated me well. Seriously inhumane people. Moreover, they have made fun of my religious belief as I was carrying lord Krishna idol with me which is highly unacceptable. Our connecting flight got delayed and for providing the information regarding next flight and other immigration there was no guidance provided at the airport. I am really disappointed with the airlines as they have hurt my self respect as well my religious sentiments during my whole flight.

The only issue we had was damage checked in bags, out of 8 bags only two arrived at the destination. Out of 6 remaining bags one came late at night and it's all broken. Still awaiting 5 more bags to come.

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Other than the inflight video screen freezing for about four hours everything else was brilliant.

The flight was dirty. The screens were not working and people were restless. Food and staff was okay.
