They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

I liked that there was a smaller airplane on LED - HEL route: it gives more "feeling of flying" than the bigger planes do.

I didn't like the fact that it was not indicated in advance (when the tickets are sold) that LED - HEL route is operated by a different airline, even though that airline is a Finnair's partner. It would have been better to have a complete information up front. But the airplane and crew were excellent.

I think this airline has an attention to detail and level of service which surpasses most other airlines. Whilst remaining competitive these factors make traveling with Finnair a far more comfortable and attractive proposition for me. In addition, Helsinki airport must be one of the best around.

for the second time on this flight, the onboard devise for credit cards would not accept mine. this is the same card i used to book the flight. i complained to british air last time but they obviously haven't fixed the problem. there seems to be a problem using american credit cards these flights. is is a problem because nothing is free. luck;y a flight attendant did feel bad about it and gave me a glass of water

I have to rate British Airways as a 10 out of 10 in almost all categories...comfort of the plane, food and service, boarding, notifications, crew, etc. In particular, the long haul flight from London to Seattle everything was truly top notch!

Their baggage handlers damaged several parts on my checked-in luggage...three zipper pulls and one clasp. What are they doing with the bags? How can they damage so many things in one fell swoop? This is a good quality Atlantic suitcase. Also, on the short flights, in this case Madrid to London, they are now charging for EVERYTHING...even water and coffee. They said it was a new policy as of 1/1/2018.

Everything went okay for us on this flight. In the future, I will suggest to my wife, who books air travel for us to read the fine print. The cost to check a bag was $100.00 which would have run us $300.00 for the trip: Boston to Brussels with a layover in Reykjavik, but on the return Brussels to Reykjavik with four days in Iceland and the return to Boston, so there goes the cheap flight! I did enjoy the in-flight movie and a documentary on the return trip as well.

My own earphones on the flight from Brussels to Iceland did not work. I could not plug them into the system.

The flight did eventually take off, unlike a few others leaving around the same time.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.
