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

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

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

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.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

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.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. 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 .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

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

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

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.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

I liked everything about the flight. The service was excellent!

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

The crew were really great, but the 4 hour delay in small chunks was the worst.

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

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Good. The wife was not working but then it got resolved.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

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

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

A disaster, I lost my connection due to overcrowding at the Miami airport, having a 3-hour layover and the airline did nothing to reboard me on time and I had to sleep on the floor for 18 hours.

The flight was 90 minutes long and the stewardesses were extremely slow. I was in row 16 and they did not serve us drinks until we were descending for landing in a 90 minute flight. Unacceptably slow and at least 10 rows (20 to 31) did not receive any drinks or snacks for the entire duration of the flight because of the slowness of the stewardesses. There is no rationale to delay beverage service to brew coffee for a flight at six p m.

Flight was delayed three hours waiting for the flight crew, even though the plane was at the gate for the scheduled departure

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

Seats in coach aren't padded enough for a 6 hour flight

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.
