Moscow airport’s great. No way can you hand in your luggage erarlier than 3 hours prior to departure. And check-in opens only at 7. This means I had to wait first two hours for check-in to open. Then wait 3 hours to be able to drop my bag, 2 hours til boarding, and finally 1 hours till departure. No, I didn’t plan on having a few hours of consecutive sleep anyway so that’s great!
