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.

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.

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.

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

Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

I had economy plus and it’s definitely worth the price. The seats are so comfortable, so much space, great large TV screens, and you get fed often. Really decent food (although other fish was overcooked.) They do need better movie choices. The crew is the best. Super friendly and accommodating. So much better than most American run Airlines.

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

Best airline to travel on a budget- really like their reasonably priced access to the SAS lounges where available.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

Flight was delayed slightly but was very smooth. It was a short flight but comfortable.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

I didn't like much about this flight. Almost no entertainment choices...and not available what was listed. Food not good.

Terrible. This airline will cancel flights at very short notice.

I would not fly again with Discover or Lufthansa. Every leg of the flight was either late (3+ hours) or cancelled at short notice. No alcohol supplied unless purchased.

Overall good experience, just the delay of 2.5 hrs was a bummer.
