Turkish Airlines enforces its published baggage limits with moderate to high strictness, particularly regarding carry-on weight restrictions and dimensions during peak travel periods or on fully booked flights. Economy passengers are permitted one cabin bag weighing up to 8 kilograms alongside a personal item. Gate agents frequently monitor oversized or heavy luggage, and bags that exceed the designated limits may be subjected to mandatory gate-checking into the aircraft hold alongside applicable excess baggage fees. Passengers are strongly advised to weigh and measure their bags prior to arriving at the airport terminal to avoid unexpected gate charges.
