10.0 Wonderful
I love this company for comfort, cleanliness on board the liner, excellent food, very good selection of films in Russian. Looked with pleasure. And the main friendly conductors who work smoothly and with the soul.
A
6.0 Okay
American Airlines told me that I have 3 other flights in which I did not book! They told me to check with you kayak - cheap flights, my travel agent. Upon calling the person told me “ not to worry “ about these flights in my name?!?!? I never booked any of these other flights. I will not ever use this site again because of putting flights in my name that I didn’t book.

Staff went above and beyond with their care for us. Flight attendants were very attentive to our needs. Food seemed too rich and too salty. Flight was fine, even with turbulence at points.

It all went very smoothly, love the new planes and cabin crew upbeat and friendly Food ok, but that is the hardest part of it all
M
8.0 Very Good
Amazing crew, safe and clean plane. Downsides were related to WiFi that only worked 3h in a 12h flight and I paid for entire flight and the food that was too intense, nothing clean to eat. Route was a little bumpy during most of the time.
