Chaos at the gate, TV displays facing the side wall instead of the waiting area, we couldn’t see anything. Need more organization in line. Also, why there is no charger on board for cell phones? No TV entertainment or music or anything. It was clearly lacking the sophistication and class of Lufthansa.

The flight did eventually take off, unlike a few others leaving around the same time.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.

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.

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
