Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

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.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

The space is tight. Either you sit straight up the whole time, but the minute you relax, your knees hit the back of the seat in front of you. My seat would not recline so I was quite uncomfortable. Didn’t use my tray table bc it was stained and sticky and nasty. I was also seating in one of the last rows and one crew member and people going to the bathroom kept hitting my elbow resting on the armrest.

Flight was delayed for 2h. Announcements were poor and I was given 1 biscuit and a bottle of water as consolation. Not happy.

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

The crew’s professionalism was top notch and the food and drinks available were excellent. I only ask that we get the refurbished 777’s on the London to Bermuda route that I had for the London to Singapore leg. The updated infotainment system is much better than the older version

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.

The staff were fantastic and couldn't have been more accomodating; however, the air-conditioning was broken in our section of the aircraft, leaving us feeling extremely cold and unwell on arrival in Johannesbury. The head sets were also faulty, causing difficulty when listening to announcements and entertainment.

The 737-8 is too small for the length of flight especially if there are any delays

The flight was delayed over 2 hours, we should off left the plane2 late passengers as it’s not fair on everyone who’s followed the rules.

Dreamliner. Yes great if maintained. I didn't see anyones screen work consistently during either of our flights. Worse was their ability to not only dump you out of premium but separate couples and seat someone's carer at the opposite end of the aircraft. This poor gentleman had no hand so his partner who assists him, being seated at the other end of the aircraft, well that really showed us all what Tui think :( It was fairly dire all in all, they advertise all the perks of the dreamliner only in reality you don't have the features and they change the windows and colours to suit their constant sales pitches. Ironically they were so low on stock for the return flight that all their sales pitches were a waste of time! Their contract only favours them and 'operational changes' well they cover every excuse and Tui use it. Surprisingly we haven't reinstalled the Tui app or booked with them since. It's a shame as I rated them highly during the pandemic.

One flight attendant not wearing a mask over nose, 50% of passengers not either, and no effort to correct. Boarding was very late with no information - lots of standing around waiting.
