Istanbul scores 8.5/10 on FlightLogic with strong facilities (8.8/10) — lounge score 9.0/10
Overview
Massive new hub designed for Turkish Airlines with impressive lounges and growing route network.
Turkish Airlines lounge and terminal
The Turkish Airlines Business Lounge at IST spans over 60,000 square metres — one of the largest in the world — with multiple dining areas, a cinema, golf simulator, museum section, and prayer rooms. Business class and Star Alliance Gold passengers on Turkish Airlines access it free.
The single-terminal design means all connections are airside without inter-terminal transfers, but the terminal is vast — allow generous connection times of 90+ minutes for international-to-international connections.
Istanbul as a connection hub
Turkish Airlines flies to more countries than any other airline, making IST ideal for reaching secondary cities in Africa, Central Asia, and the Balkans that lack direct flights from Western Europe.
Compare IST against DOH (Qatar) and DXB (Emirates) for similar Europe-Asia routings — Turkish often wins on fare price; Gulf carriers win on premium product consistency.
