Malaysian here. With the visa exemption scheme,
1. How many times can I fly to Thailand in a year?
2. What's the maximum total length of stay in Thailand in a year? (multiple entries). For example, 180 days in a year regardless of how many entries
Couldn't find this info easily. Appreciate the valuable information given here.
TLDR : Answer Summary
Malaysian citizens can enter Thailand under the visa exemption scheme as many times as they want by air, with no officially documented maximum stay or number of entries. However, after multiple entries and lengthy stays, immigration officers may question travelers, particularly if it appears they are attempting to reside in Thailand long-term on a tourist exemption. Recommendations vary from frequent travelers to take breaks in between stays to avoid scrutiny.
