Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

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

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

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.

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

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Flight with Ryanair more than 1,5 hours are awful... No space between seats, absolutely uncomfortable stay.

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

Short flight, some waiting to board, but no issues and no frills.

Pros: "Nothing,except I got to my destination safely"
Cons: "Everything.They don’t ever offer you WATER in a 10 hour flight!! Check in crew rude. Attends dismissive to rude."
Pros: "It got me to my destination. Nothing else to like."
Cons: "Boarding was a circus. The most disorganized I’ve seen. Price-gouging at every turn. Cramped uncomfortable seats. And of course the nonstop screaming infant."
Pros: "Nothing"
Cons: "If I was allowed onto my flight. My previous flight on AirEuropa was overbooked, I didn’t get a seat, and they put me on the next flight out. With the delay I didn’t get to the check in window till approximately 55 minutes before departure. Norwegian wouldn’t even let me check in. They said boarding had already stopped and the flight was closed. Sent me to the sales rep where I was told my only option was to switch to the same flight the following day, but that would cost me an additional 630€. I ended up stuck in Barcelona overnight and found a cheaper flight home with British Airways/American Airlines."
Cons: "Flight delayed and gate 9 in terminal 1 at JFK is a nightmare. It’s in the corner and you can’t hear any announcements at all. Horrible place."
Pros: "We landed safely."
Cons: "The operating flight was changed and our seat were downgraded. Given that it was a birthday trip i wanted my fiancée to be as comfortable as possible. Instead she was stuck in a middle seat between two crying babies with no outlets to to charge our phones for entertainment. Additionally I was notified that I cannot be refunded until after the flight has landed. So technically Norwegian still has my money and I paid top dollar for a less than average experience. Unacceptable."
Pros: "The entertainment was actually great. Literally everything else was terrible."
Cons: "It was the most uncomfortable flight ever. No water served and no refreshments served at all on the 9 hr flight."
Cons: "No food or water was offered. Had to stop for water . Barely any selection of movies"
Cons: "It would be great if they had free drinks and snacks"
Cons: "Online check in could be available immediately. I don't want to waste long time just for check in when I don't have luggages to pay. You could save time too many people."
