Do they have check-in kiosks at T1? Could you have printed a bp from one of them--avoiding waiting in line to see an agent.
Not for SU.
Judging by what the Aeroflot people initially told me, it would have been pointless anyway. Because initially they mentioned that I needed a "real" BP for "passport control". Passport control. On departure from the US. Right. Further into the conversation, they made it more precise that *they* wanted to check my passport etc. My reply that that's what gate agents are for, in the civilized world at any rate, didn't meet much understanding...
