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

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.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

The flight was fine but no food available apart from snacks like Pringles and olives which was a problem for me as I hadn’t eaten anything that day. But the worst problem was BA left 24 suitcases in Heathrow as the flight was too full but didn’t tell anyone. So we waited for ages at Toulouse airport with no information and finally found out from the one member of staff in the baggage collection area who explained what had happened and apologised for no announcement being made but said that was their policy. Then BA contacted me today to say they have found my luggage and can deliver it to me on Tuesday - half way through my holiday!!!! So a friend has had to make a four hour round trip in his car to go and collect the luggage from the airport so we can get it today. A TOTAL SHAMBLES AND DISREGARD BY BA FOR THEIR PASSENGERS’ BEST INTERESTS.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

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.
