Arrive for 56 days.
Onward tickets. I know the airline will question me, but will Thailand Immigration.?
Been there a few times but generally for a month.
TLDR : Answer Summary
Travelers staying in Thailand for 56 days often question whether they will need to show onward travel tickets upon entry. Based on community experiences, immigration rarely asks for proof of onward travel unless there is a specific reason for suspicion. It is generally recommended to prepare an onward ticket if the airline requires it for boarding, as they may deny boarding without one. Obtaining a 60-day tourist visa in advance can circumvent this requirement entirely, making the entry process smoother and potentially more economical.
