Hello,

Is is possible to walk airside from the domestic terminal to the international terminal in IST or vice-versa?

My wife, me and our small daughter will be connecting from Cyprus through Istanbul Ataturk Airport - but they are both travelling (on a separate booking) to London (so need to check in), whereas I am continuing on Atlasjet to Antalya.

There's a 4-hour layover between our arriving flight and her flight to London, and I have a PriorityPass membership that can get us all into a lounge. The problem here, of course, is that I will be flying domestic, so I assume our departure terminals would be different.

If walking between the terminals is not allowed, could I be even let into the international terminal with my connection/boarding pass? (As I said, we are all arriving from Cyprus then going our separate ways, so maybe I could just get into the international terminal then get out and get through security again).

A 3rd option is just giving her my PP card and hoping they don't cross-check the name.

Thank you for the advice.
