If you're the Producer and you have to return to Baku on a Sunday, the only option is to fly via Moscow.
Kyiv to Baku via Moscow: what, as they say, could possibly go wrong?
Let's examine the variables:
1. Your flight's on Aeroflot, which "isn't that bad," as long as you're flying outside the FSU. It lives up to its stellar reputation for style and service on those "internal" flights;
2. You fly on a Tupolev, which "isn't that bad," as long as your comfort and maintenance standards are fairly low;
3. You fly via Sheremeteyvo, the totally ghetto Moscow airport which serves Crapistan, including the flights to Baku and Yerevan, which leave at the same time from the same gate;
Alas, there's nothing really to report, other than a bunch of drunk Russians throwing up in the aisle during the flight from Kyiv. Nothing unusual about that at all.
