Positive: It was refreshingly easy and polite check-in and boarding staff. Flight was on time and Helsinki is a very well-signposted airport. Shopping was nice as well. Flight was not full and I had lots of space in economy. Flight was perfectly on time. Negative: Food and drink not very good, but that it is normal on any airline. Didn't expect anything else.

Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

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.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

It was good experience this time. The flight was on time.

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

Overall, my last three trips on American Airlines have all been either delayed or "rescheduled" due to mechanical issues. At least on delay caused me to miss two possible connecting flights each later than the first. My last option for my last connection required the assistance of the onsite service desk (O'Hare Airport). The wait time for the service desk was such that it jeopardized getting booked on the last connecting flight available for the night. Suffice it to say, my latest experiences with American Airlines have caused me extensive loss of productive business and personal time and can therefore be classified as significantly less than satisfactory.

Waiting for gate in RDU for more than 20mins is crazy.

American Airlines was great and worked very hard to change my ticket so I could get an earlier, direct flight back to Dallas. However, I was informed that Kayak made mistakes with my itinerary and classified my ticket as desiring to be on the earlier flight instead of taking the necessary step of calling AA to get me on the standby list. This ended up keeping me from being added to the standby list and delayed me getting home by 6 hours. I am happy to discuss this further with Kayak so they can correct their procedures so this won't happen again.

Waited for oxygen tanks for 30 minutes after boarding was complete.

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.

Flight from CHI to PVD was delayed by over 20 hours.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

Delayed departure Madrid to Lisboa and my luggage no arrived

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

Wonderful just hope the had more direct flights to Boston

Very long line at the gate, moved slowly. I had expected that boarding a flagship A330neo would be with a jetway directly at the gate, and not a long bus ride to the airplane.

The layover was only one hour and a huge line for passport control. If I didn’t cut the line and argue was every single official, I would’ve spent the night in this one. Obviously.TAP AIR people. do not take into account.this problem with their flight scheduling, which is extremely frustrating. Poor food choices, on the pasta was offered, they ran out of chicken right away. All the sodas and water poured in a tiny 70 mL cups, which is not enough to keep hydrated on the long flight. I had to ask for 34 cups at a time. Flight attendant seemed to be tired and overworked.

I am not very tall, and had a difficult time getting my carry-on placed in the overhead bin while passengers were behind me waiting to get to their seats. After struggling with the luggage, I turned it around, and left it, knowing it was not properly placed, but believing there was adequate room for it in the bin. When the flight attendant came through the cabin, she asked whose bag it was, and scolded me for not positioning it correctly. She turned it around and moved on. I thought that her approach was totally unprofessional, calling out a passenger in that manner.

30 minutes still don't have gate number, ask many people can't get answer.

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

the seats were bad and uncomfortable and the food was not tasty.

The crew was amazing. I appreciate the level of professionalism in the Iberia crew.

A more organized boarding experience and better food would have made the experience better.

Flight cancelled, lost a day of travel where we were trying to meet friends we couldn't meet. Iberia website is very difficult to navigate and has lots of dead links. If you do not speak Spanish it is even harder. Tried communicating on their WhatsApp and that was also close to impossible. We were told we'd be compensated 150EU's for this cancelled flight but there is no avenue towards rectifying this issue. I've had to take it up with my credit card to contest the charges and not pay for a flight that didn't happen but doubt I will ever be reimbursed for my two Ubers to the airport where we never even departed or the 150EU's we were told we would receive. I would never fly Iberia again. Clown show.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.
