If I fly through Bangkok and then through to Koh Samui all on one ticket can I leave my bags until I get to Koh Samui and then go through immigration there
Or would I have to get my bags and go through immigration in Bangkok and then take a regional carrier through to Koh Samui
TLDR : Answer Summary
If you are flying to Koh Samui from Bangkok on a single ticket, you will typically go through immigration at Bangkok. Your checked bags may be transferred directly to Koh Samui, depending on your airline's policies. It is advisable to check your ticket details and confirm with your airline about baggage handling before your trip, as there could be variations in procedure based on the airlines involved.
