We're booked on TK721 (BOM-IST) with a mind-numbing 5:55am departure. I'm interested in experiences with this flight and negotiating BOM T2 at that hour. We'll be in business, and I expect to be able to do online checkin, but we will have bags to check.

What will T2 be like that time of day for someone flying TK premium cabin?Is a 4:30am arrival about right? Any general comments on J service on this flight?
