I bought 2 tikets from Chicago to oscow and back for me and for my son. I live in USA, son lived in Russia but he received immigration visa and I had plan fly to USA with him. From Chicago I used my ticket and say SWISS staff what my son will have trip only from Moscow. I paid for 2 tickets around $1700. Today when we should have trip back to USA, SWISS company said what ticket for my son do not exsist. And I spent for new ticket 220000 rubles about $3600. Nobody in SWISS company do not said me what my tocket for son canceled. I am shoked !!!

I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

Most Improved Player - Finnair has done the best experience in overall long haul flights out of the 40plus airlines I have flown in the last 3 years; brand new planes, nice and diverse cabin crew, beautiful lightings videos details chocolates etc, best entertainment system in the industry, and things always go smooth in Helsinki airport. Awesome imrpovement over recent years.

Big struggle for airlines still remains varying quality customer service. Finnair still seems to struggle with this occasionally. Finnair can work harder to keep customer service quality high. Hate to say it, but perhaps letting the bitter, last generation flight attendants who seem to have a grudge about the decline of the glamour and benefits of the job as flying has become commonplace with more competition (seen this on Finnair & N America’s older airlines line United)

I like Finnair, the crew, the service.

I was not able to check in online within the 24 hrs prior to the flight as the Iberia system kept flashing and "error"message. Therefore, I was not able to pick a seat, which I would have paid to upgrade if necessary, but instead I was assigned a middle seat as a last option, at the counter, and paid for an exit row which, except for the leg room, was just as uncomfortable!

It was late both going to Prague and coming back. Then on this flight the stewardess tried to tell me that I could not put my bag on the bin on top of my head - she was reserving it for other passengers! Then she realized that her comment might sound racist (so she apologized), then she told me that I could not put my small bag under the chair. Finally I told her that she is certainly looking for a way to get me off the flight to which she answered "I can certainly find something!!!" Cultural sensitivity is needed with these stewardesses who are racist like I don't understand and I was certainly polite!

On board entertainment ststem has lots of options to choose from on all accounts. Food selection was good, served hot with large selection of drinks. Overall much better than US airlines that cross Atlantic.

More comfortable seats for long haul flights is a must have. Comfort+ Offered a money’s worth alternative to business or first class. Boarding is done away from terminal building which required busess for transportation back and forth. Prefer skybridge instead.
