Collect at IST when you are ready to leave the city.
Istanbul Airport is a single, very large terminal. Rental desks and meeting points are on the arrivals side, and some companies hand over cars in the multi-storey car park. Walking from the gate to the car can take a while, so allow extra time after landing and keep the supplier’s phone number handy.
Think about when you actually need the car. Central Istanbul has heavy traffic, limited parking and excellent public transport, so many travellers spend their city days without a car and collect it on the day they leave for Cappadocia, the Aegean or the Black Sea. You can also return a car here before a flight and avoid driving in the centre.
If your route continues into Asia, compare this airport with Sabiha Gökçen on the Asian side. Starting there saves a Bosphorus crossing and an hour or more of city traffic.
