Two security layers plus a huge single terminal make a late check-in expensive.

Landside X-ray, then passport control, then a long walk or buggy to the pier. Turkish Airlines Fast Track passport counters sit on the left of the international desks for Business, Elite, Elite Plus, Corporate Club and Star Gold.

Stay airside and follow Transfer / Connecting Flights — you still re-clear transfer security.

International-to-international: arrivals down to the transfer level, X-ray in the middle of that floor, stairs up to international departures. Under 90 minutes, use the short-connection / hotpoint ports in each pier. Do not follow arrivals/immigration signs unless you are ending in Türkiye.

Airside food is fine; the TK and iGA lounges are the reliable sit-down.

Turkish Airlines Business (escalators opposite Gate E1) is the food destination for Star Alliance Business. Everyone else with a card should use iGA International on the mezzanine after passport control, left toward the LCW escalator — not the SkyTeam lounge, which is not operating.

No strike or terminal closure on 25 Sep 2026; check live waits in the iGA app.

Runway 09/27 opened 18 Sep 2026 as the first east-west runway. Use the iGA site/app for live checkpoint waits rather than assuming construction chaos.
