Questionary would have N/A available, I did not eat, can't say I'm either sad or happy with that.

budget airline, you get what you pay for but pilots flew great, crew was awesome!

Delays, uncomfortable, and no compensation or free water after being stuck in the plane for more than an hour!

Flight was 1 hour late. The luggages also arrived 45 minutes late.

The flight was delayed by 1.5 hours & the gate was changed, so it was a long walk from the 1st gate to the 2nd gate. The bags took about 1 hour to arrive after landing. Ridiculous wait for bags for which we paid extra $$$$$$$

The upholstery of our seats (7A+7B) were in bad shape: twisted, hard and uncomfortable. We also had a 55 minutes delay. Apart from that everything was OK.

We arrived on time to our destination and the flight was peaceful (and short!.)

30 minutes late as usual. Could not pay for any food or drinks, despite using three cards. Amex, Mastercard and Visa. Uncomfortable seats

Norwegian ground crew did NOTHING regarding priority boarding. I paid for priority and there was no priority boarding effort made AT ALL at the gate.

I was not well I have got high temperature there for I never made to to airport

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

Empty seats next to me - wish it had been for a longer flight!!

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Delay, luggage didn’t arrive. Had to go the next day to collect it

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

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.

Excellent service and always our preferred choice of airline. Was surprised we had to pay for soft drinks though. Other wise great airline and customer service!

Better food; taste, portion. Bottle of water per seat was great.

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.

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

I liked the free wifi in business class and the food and beverages.

I paid for the seat with more leg room but on the day of my departure my seat was changed. I brought it to the airline costumer service and he was able to change it back. The person sitting next to me had the same exact issue.

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

The check in not ok! Demanding that we check our carry ons on check in! When there was plenty of available space inside the plane! And the staff at check- in was rude and not helpful and I was traveling with my autistic son and his service dog! Boarding was easy since we were priority boarding! The crew was ok expect from one guy flight attendant that was actually great!

Please see my comments for the flight from Chicago to Copenhagen

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!

Passengers need to be consistently told by the stewardesses to position their seats up from recline when eating. This is not something passengers should have to request. Common courtesy...

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Ground staff a baggage drop in Palma were generally unhelpful. The flight was delayed and the boards were never updated and there was no communication on the length of the delay.

Over 2 hours delay, communicated last minute - and no acknowledgement by flight crew

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

Notified as to why there’s a delay with our flight.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board
