SAW · Busy Pegasus and AJet hub with strong 2026 punctuality and cheap metro and coach links, but crowded halls and lounges at peak times.
IST · Huge single-terminal Turkish Airlines hub: excellent TK and iGA lounges, unlimited Wi-Fi, and a real metro, offset by two security layers, transfer re-screening, and long pier walks. 2025 traffic was 84.4 million, not the 90 million capacity slogan.

Budget three hours for originating flights
Two security layers plus a huge single terminal make a late check-in expensive.
Transfers still go through security
Stay airside and follow Transfer / Connecting Flights — you still re-clear transfer security.
Lounge first if you have access
Airside food is fine; the TK and iGA lounges are the reliable sit-down.
