Booking tips
- Departures from Gaziantep are cheapest mid-week (Tuesday–Thursday). Friday evening seats sell out first.
- Overnight buses save you a hotel night and arrive fresh in the morning. Book the upper deck, window seat, away from the rear bathroom.
- Confirm which terminal your bus departs from — İstanbul may have multiple otogars depending on the operator.
- Set a FrogSky price alert if you're flexible — fares drop in mid-week pockets you'd otherwise miss.
