I'll be flying into Istanbul on Apr 13th and traveling around (Cappodocia, Selcuk, Palmukkale, Lycian Coast, Antalya) until May 3rd. On May 3rd my return flight to the US from Istanbul on Turkish Airlines leaves at 11 AM from Ataturk. My question is, is it OK to fly back from Antalya on the morning of May 3rd to catch my 11 AM flight (on either Onur, Atlas or TA)? Also, how early should I be at Ataturk to check in for my 11 AM flight and will I go through passport control there? I just want to make sure I don't miss my flight home.
Also, my girlfriend is leaving on Sunday the 22nd from Istanbul on a 10:40 AM flight and I am hoping to get her a flight back from Izmir that morning. Any separate concerns for this?
Thanks in advance.
