I've read a few of the IST Layover threads at FT and see that it will take me 15-45 to clear customs upon arrival but I haven't see anything about getting back to the airport. I have two layovers coming up next month (both on a Saturday if that matters). For the first layover my flight lands at 4pm and departs at 1:10am. For the second layover my flight lands at 5:45am and departs at 1:20pm. I'm arranging a for a tour guide to pick up/drop me off at the air port. Multiple guides have suggested to use the second layover because even though it's shorter, more will be open. If my flight is at 1:20 what time should I get back to the airport. My bags should already be checked, I should have my boarding pass, and I will have applied for an e-visa in advance. I'll be traveling to the US on a united business class award ticket if that matters.
