Some international COP31 visitors may use Istanbul as their first arrival point before travelling onward to Antalya. An Istanbul airport transfer plan can make the first part of the journey easier, especially when a hotel stay, a separate domestic flight or a group arrival is involved. Istanbul has two major airports: Istanbul Airport (IST) and Sabiha Gökçen Airport (SAW). They are not interchangeable, so the airport code on the flight confirmation should be checked before a transfer is booked. Include the flight number, terminal where available, hotel address, number of passengers and luggage in the request. For an overnight stay, arrange an Istanbul airport transfer to the hotel and a return pickup for the next flight separately. If travellers land at one airport and depart from the other, allow substantial time between flights and request a direct inter-airport transfer only after checking the schedule. The final Antalya airport transfer can then be arranged around the domestic arrival time. Teams travelling together should confirm vehicle capacity for bags, equipment and child seats if needed. Keep a reachable phone number active after landing and send updates if a flight time changes. Clear pickup instructions help the driver and travellers find the meeting point. This is not an official COP31 transport programme. It is a private airport transfer planning guide for attendees organising their own route through Istanbul and onward travel to Antalya.
