Onward ticket requirements for Thailand in 2026
A complete breakdown of when Thai immigration asks for proof of onward travel and how to handle each situation.
Thailand requires proof of onward travel from many travelers, especially those flying on one-way tickets or arriving from countries known for visa overstays.
Who gets checked?
•Travelers arriving on one-way tickets.
•Travelers from certain nationalities (varies by airline check-in policies).
•Travelers staying longer than 30 days.
What works at Bangkok and Phuket airports?
A verifiable PNR from a major airline is the safest option. Thai immigration officers can check the PNR on their internal system, and the reservation must show you leaving Thailand within the permitted stay period.
How long should the reservation be?
For a 30-day visa exemption, the onward flight should be within 30 days of your arrival.
For a 60-day tourist visa, within 60 days.
Common pitfalls
•Don't choose a reservation that "leaves" before you arrive.
•The departing airport should match where you actually plan to leave from.
•Names must match your passport exactly.
