It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

6.0 GoodAnonymous, Jul 2025HEL - DFW

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

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

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

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.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

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

Pathetic check in experience once again. Not enough staff scheduled at bag drop or for special assistance at LHR. Really need to rethink the whole self check in procedure. The crew was good. A very decent selection of special meals in this leg as compared to the JFK-LHR leg.

Very clean and comfortable cabin. Amazing Mediterranean salad for lunch before landing. Great range of films to watch. Really quiet and easy to sleep on the flight also. The initial food was a bit weird: odd fried chicken pieces in some weird white gloop, but that would be my lack of cultural knowledge on the grub. Salad more than made up for it at the other end. Staff were super attentive and helpful. Great and easy flight

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

The flight crew were friendly and attentive. Food was good and they passed out ice cream and drinks awhile after Lunch was done. The ice cream was a nice treat! I found several movies to watch during the flight. There was many movies and tv shows to choose from. We flew Premium economy and there was enough leg room to be comfortable. The seats were also comfortable. I would fly AA again if the airfare isn’t expensive.

More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

Gate check bags that had to be gate checked because of first flight being a small flight are missing. British airways lost the luggage and haven’t met up with them yet!

Staff lovely , economy seats very uncomfortable , wheelchair assistance wonderful in Heathrow awful in Nashville !

Good crew and a great experience. Only good things to say.

Great thanks - a whole row to myself. Good food but film selection not great.

It is okay. Flight was on time to start and early to land

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.

Great entertainment choices. The crew was extremely kind and accommodating. My remote control did not work. Too little space between seats. Arm rests only go up a few inches making less comfortable.

Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

Boarded smoothly, took off on time. Entertainment screens were reliable and the movie library is abundant. Food better than wtst was served on the first leg of the journey by another airline.

Check in was incredibly fast, fukuoka was comfortable and crew very pleasant. The only negative was that the boarding was somewhat chaotic, but it so often is these days as airlines tend to board by how much you pay and not by what an orderly process of filling the plane would be.

It was ok. Even after the airport bus took us to the terminal , we did not expect to walk 35 mins inside the airport to the gate . A 15 min walk is ok . Especially if there was any delay in TSA check which happens to is too then people can easily miss the flight.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

All good. Loo’s weren’t great and as clean as i would like.

A great flight. The crew was excellent too. Of particular note of excellence was the gluten-free meal which was one of the best offerings I’ve ever had on a plane. Outstanding work, BA chefs.

I was put into business class. Wow! My flight attendant was great! The food amazing’

I got stuffed on both flights into terrible seats. Second flight the seat didn’t even recline and fit s tall person, that’s very uncomfortable.

I arrived at Bridgetown only to fins that a suitcase was missing. It was left at Manchester. I had to wait wait 2 days before deciding on going to collect from the airport personally. I am not happy about paying for baggage at the airport. This I thought was included in the price of the ticket. Who goes away for 2 weeks and does not bring luggage. This was a total rip off and I am not happy. I need someone to contact me before returning so that I don't have to pay all over again to return homde.

Boarding market okay just because of the delay we had, but not related to the crew in any way…

Not so good with their baggage handling as they damaged one of my check in luggage
