My bag was delayed in London, so I didn’t have my belongings for 24 hrs after I returned home. They did find it and delivered it to my house, which was appreciated. The flight itself was great, and the staff was fantastic.

My bag was delayed in London, so I didn’t have my belongings for 24 hrs after I returned home. They did find it and delivered it to my house, which was appreciated. The flight itself was great, and the staff was fantastic.

Our previous flight was delayed but they waited for us to board.

Arriving at Heathrow was a complete disaster because air bridge broke down and it took ages to find spare stairs! Something that I'd kick Heathrow in the shins for, not Finnair - who were great.

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.

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

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.

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

Food was pretty poor - bland, tasteless. Drinks offerings were very limited also.

This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

I feel the service staff do not treat American customers well. I also feel there may be discrimination against minorities.

Nothing to answer your questions appropriately. It was just a 2hrs flight from London Heathrow and we were served a cup of tea only. So the questions about food aren't relevant and also, there's no entertainment on these short haul flights. Overall, the flight ✈️ was okay.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

SAS is very good at service, the lounge was great, and flights were on time. Boarding is fast and efficient!

Flight & service all top notch but online check-in a poor experience. Clearly a glitch on their website which prevented completion via my Android device. Also no easy way to provide this feedback to the airline so they can fix it!

Flight delayed 3 hours 45 minutes. Connecting flight changed. Would have missed cruise ship. Had to cancel return flight, because we couldn't just cancel flight to Nice.

Good and drinks could be better. My checked baggage was damaged

Good friendly service and food - The seats in business class are old, too hard and not very comfortable.
