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

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

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.

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

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

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.

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

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

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.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff for a fantastic friendly nice we came round and check we need anything else to eat or drink

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

I got rerouted to another flight/city because the original flight was late and I would not have made my connection. I had to wait an additional five hours (no compensation) for the new flight which was also delayed because the computer was not working. Arrived at my final destination after nearly 20 hours of travel only to discover that my baggage had not arrived with me. Two days later and still waiting for my baggage. Customer service has been incredibly unhelpful and even hung up on me because I dared to ask for them to have someone call me when my bag arrived at the airport. No one apologized to me for what I experienced and they were dismissive of the fact that I have absolutely no clothes or toiletries. Absolutely awful, disorganized and stressful experience. Am dreading the return flight.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

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.

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

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

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

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.

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.
