Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

Great experience. Typically do klm to Amsterdam but may start taking this flight in future - greatxexperience.

Boarding required going up and down the stairs with your carryon bags which wasn’t an issue for us but would be quite challenging for elderly people, or anyone with mobility issues.

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!

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Travelling coach, comfort is all in one's perspective. Movie choices were great. Food was OK. Flight crew were pleasant. Tip: If they come through asking if you want tea or coffee, do not ask for water. They get miffed. So use the call button after they pass through.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

Sat on runway for 1.5 hours waiting on winds to change so we could take off. The pilots did an amazing job getting up in the air when they had permission to take off.

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

Very helpful in getting us off the plane first to make a tight connection.

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

Long 5 hour and 45 min flight and only one drink service and cookie snack

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

Bigger seats. Board back to front! Disembark front to back!

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

Good legroom. Attentive crew. Wine quality poor, you can do better

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

Great experience. Flight was on time and reached destination on time

I meant this flight was not good, the one from Tirana to Frankfurt was better!

Easy checkin. Things went off without a hitch. The the movie selection for the flight wasn’t great, though.

food, movie entertainment upgraded current, interconnecting flights being on time, we have a 24-hour overlay

Exit row seat that cost extra to book had a bad monitor marked as out of order, so clearly something they should have fixed.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

Never happened. Flight was delayed. Had to be re rojyed

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

The food was very good and it came multiple times

Flight from LGW to JFK delayed by 4 hrs No explanation given until the pilot said the delay due to planned maintenance on the aircraft

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.

bad, made it to connecting flight and they didnt let me board

More space, of course. a footrest! more room to walk. Movie selection was awful. Some good documentaries would help if the movies can't be better. The flight itself was great, crew was great.
