I liked that there was a smaller airplane on LED - HEL route: it gives more "feeling of flying" than the bigger planes do.

I didn't like the fact that it was not indicated in advance (when the tickets are sold) that LED - HEL route is operated by a different airline, even though that airline is a Finnair's partner. It would have been better to have a complete information up front. But the airplane and crew were excellent.

Secondly, the air was turned down, I guess to conserve fuel, and the plane was unbearably hot, And at no time was food offered for purchase or even a beverage service. I have flow AA for 20+ years and this was the FURST flight I have ever experienced. Sadly I believe it will be my last!!!!

Nothing remarkable

I got up to use the bathroom and I was seated in the 10th row. When I was trying to make my way back to my seat, the beverage service had started. They were at the 12th row and after bumping into me, the flight attendant asked me to back up and wait until the beverage service was over to go back to my seat. This was a flight from Frankfurt to Zurich, only about an hour long, and I would have easily spent half of it standing up had I complied with their request. I had to be pushy and ask them to just back up the cart 2 feet so I could get to my seat, which only took them 5 seconds. This was a very rude, illogical, and unreasonable request from the Swiss Air crew.

The crew was lovely. Really nice, and did a wonderful job with the cart service.

We ended up being deleyed about 30 minutes, in damp weather. It's not like it was snowing. Not sure why it took so long. B/c of baggage charges now everyone brings a carry on. This seems to slow the process of boarding as know passengers are asked multiple times to check baggage (for free, which is the one nice thing) before boarding b/c the overheads will be too full. Group 6 which I was in seemed like it was just the rest of the plane. Super busy, took me forever to get to my seat all the way in the back. Why don't airlines reverse board? People sitting in the back should board first. I feel like this would save so much time.

Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
