Xfer from IST to aegean airlines

I dont understand your question. Aegean flies out of IST. IST has 4 concourses. How long your connection takes will depend on many factors. Are both legs on one ticket or separate? Will you have checked luggage? What time are you scheduled to arrive/depart? Then other factors: how long is the line for passport control? If you are on separate tickets and have checked luggage, you will have to exit the secure area, pick up your luggage and check it with Aegean, then go through security to go to your next gate. If you are on a single ticket , or are on separate tickets but only carryon luggage, and have your boarding pass for your connecting flight, then you should be able to stay airside and proceed to your gate after Passport Control. Display boards will show which concourse and gate you need.

A few points of clarification from the previous response:

IST has five concourses, not four. (A, B, D, F, and G). There are also C gates and E gates, but they are along a corridor that spans the airport terminal, not a separate concourse. You can see the map of the terminal at https://inmapper.com/istanbul-airport/.

You will not have to go through passport control if you already have your boarding pass for your connecting flight. Follow the signs for international transfers. You'll go through a security screening and that will dump you into the main terminal.

Occasionally I have been allowed to bypass the international transfer gate at IST and proceed directly to the main terminal, but I think it depends where your flight originated, and I think coming from the US, you won't have that option.

If you don't have your Aegean boarding pass, you may have to go through passport control and check in again, so you should really try to get it. If you can't get it before you leave the US, perhaps you can connect to airport WiFi after you land and check in for your flight.

In any case, it's a large airport, and you'll have to do a lot of walking. But the signage is excellent and it's quite efficient. There's no straightforward answer to how much time you'll need. How much time do you have???

thank you. you provided information that is very helpful. I do appreciate it!!
