Can I book an onward ticket for 60 days later when flying into Bangkok, or do I need it for within 30 days?

When flying into Bangkok, airlines typically want to see an onward ticket. It is generally recommended to have a ticket that reflects your travel plans within 30 days of your arrival, especially since you can extend your 30-day stamp but need evidence of onward travel. Some suggestions to avoid unnecessary costs include purchasing refundable tickets, renting onward tickets online, or obtaining bus or train tickets to neighboring countries, as these can sometimes be accepted. It's advised to have a clear exit plan regardless of whether it’s a flight or an alternative mode of transport.
