IST is bigger and better connected; SAW is often cheaper and closer for some hotels. Transfer time is the real difference.
On the European side, 40–60 minutes from Şişli depending on traffic. Most long-haul and full-service carriers land here, and it is the easier arrival if you are tired or travelling after treatment.
On the Asian side, 60–90 minutes to Şişli and longer in rush hour, because the route crosses the Bosphorus. Low-cost carriers favour it and fares are often lower — worth it if the saving is meaningful, not if it is €20.
Istanbul traffic between 07:30–10:00 and 16:30–20:00 can double any transfer. We plan pickups around your flight and around the clinic schedule so you are not sitting in a car when you should be resting.
A driver meets you inside the terminal with your name after baggage claim, and the same service returns you for departure. It is included in every treatment package, both airports, both directions.
The driver tracks your flight number. Message your coordinator if anything changes — no rebooking fee applies for delays.
