We had an early morning flight from Istanbul to Kayseri via Turkish airlines and reached the airport via taxi booked by our hotel, Nowy Efendi. It came to roughly 66 TL and you need to report minimum 1 hour before the flight time. There are two security checks at the airport hence it is advisable to leave accordingly. There are couple of nice café and restaurants at the airport like Starbucks, burger king and sweets and bake. The airport also has automatic massage chairs which is an absolute stress buster. For 2 TL you get a good 3 minute massage.
