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.

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.

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

As an ex airline employee in my home country of Jamaica, it was wonderful to see that Swiss Air has maintained it's exemplary service. The crew was both pleasant and professional. The meals were wholesome and tasty. My brother and I traveled and we both agree that our amazing vacation started with the excellent experience with Swiss Air. Continue to keep your standards high 🙂

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Horrible flight. First delay in boarding of approximately 30 minutes. While in the plane, the flight attendants huddle and we get an announcement that the crew's legal time was exceeded, that they don't have replacement crew and that they will need to cancel the flight. One would think that they would know that their time was to be exceeded BEFORE boarding. Took for ever to deplane. Then we were told that flight would not be cancelled but gave us a departure time of 21.15, which of course was not fulfilled. Arrived in Valencia, luggage took 30 minutes to arrive. Absolutely unacceptable

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

Boarding we were jammed into a hot crowded bus waiting too long while another bus went in front of us. Appreciated blanket and pillow, movie available helped time pass, the food was not appealing so I had my own snacks, the flight is long, but nothing they can do about that. Staff adequate, flight good.

The business class seats were smaller and closer together than other airlines.

Boarding- Good Seat Comfort - OK Crew - Good Food - Mediocre On Time - Very Good

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Great price for really nice seats and the plane and staff were great, only 5-10 minute delays!

Tap was very frustrating in Lisbon. Not enough direction and help. Mixed messages of where we needed to go. Seats were not very comfortable.

This flight arrived late. We joined well over a thousand of other people waiting to go through customs. Air Portugal has lost my bag. We had to chase down a representative even though we had waited at the baggage claim for well over 1 hour and 35 minutes for baggage to come. No representative was there to explain the delay or to give any direction. After 1 hour and 35 minutes at least four passengers had no baggage to pick up or had a fraction of their baggage. The representative was a young woman who clearly did not have the experience to deal with what was happening. Very disappointing as of course we were dealing with great amount of jet lag and having been up for 24 hours at that point and not being able to have any of the things necessary at home that were contained in the bag was quite upsetting. That instant occurred last night at approximately 11:15 p.m. and as of 12:30 p.m. the next day I have not heard anything from Air Portugal.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

Flight was fine. Second meal ( fish sandwich on hard roll) was awful. My suitcase didn’t make the flight. It had been located, but won’t be delivered until tomorrow. Five days after flight

There was chaos at the Naples airport. We arrived three hours early for the flight but there was no invitation available about where to go to check bags until an hour later. Then we had to go to a different terminal to check our bags and check in and back to the first to board.

Everything, every step of the process, from check in, to boarding, to exiting the plane was organized, efficient, and orderly. Excellent experience!

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

Flight was 3h50 and was only provided with a packet of oat cookies and offered a cold drink. Thankfully i'd had breakfast but for a morning flight of that length some sort of breakfast should be included. There were 2 toilets for economy but due to turbulence we couldn't use them until the last 1hr which meant the queue was then huge. Would've been nice to open up the business one for those closest to the front to use.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

Cabin crew lovely and accommodating and I'll always fly BA in the future

It was perfect. The service was exceptional. I would never want to cross the Atlantic in anyone else's sardine tins.

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

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