Good flight, departing Moscow wasn't so bad even with the wintry conditions (JFK on the other hand...) Flight staff was friendly and well dressed, video worked, needs were met. Wasn't cold on the flight though I did sit by the window seat so the temperature was adjusted accordingly :) Overall, very pleased with Aeroflot. Would I do it again? Already have a trip booked in two months!

Two go-rounds due to wind sheer in the airport environment.

Our flight from BLR to FRA got cancelled because of bad weather. The agent at the check in desk immediately put us on an alternate AIr France flight via CDG to LAX, which left an hour before our FRA flight. The service on the flight was excellent. But we are most thankful for the quick re-booking on a different alternative, ensuring no hiccup. We will only be flying Lufthansa from now on, and recommending Lufthansa to all friends and colleagues.

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.

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.
