I have flown Aeroflot Russian Airlines a couple of times. I will say that it gets you from point a to b, but there are some definite issues with it. The first big issue is the fact that the ride is not particularly smooth. I'm not sure if this is because of the age of the airplanes being flown or the pilots, but they definitely are not as smooth as the American airlines I've flown. The planes are also not especially clean and they don't offer any service per se. You basically get in the plane and hope to stay in your seat the whole time and not have to use the bathrooms (going back to the clean issues). Also I have never gotten airsick from an airline trip (and I've been flying since I was about 4 years old). I did get sick on a number of flights taken with Aeroflot Russian Airlines. This airline will get you where you need to go, but if you don't have to fly I'd recommend a different travel option.
