I have a METV (expiring Apr 6) and will arrive in Thailand (Phuket) with a oneway ticket Jan 6. I will bring a return ticket Phuket-Singapore March 4-7, so I don't get into any trouble with my oneway ticket. But I don't have any other tickets out of Thailand. Could this be a bother with the airline when I'm leaving Singapore, or with Thai Immigration when arriving?
TLDR : Answer Summary
The user has a METV expiring on April 6 and plans to arrive in Thailand with a one-way flight. They are concerned about potential issues with their one-way ticket, as they have a return flight from Phuket to Singapore but no onward travel out of Thailand. Comments indicate that while it is unlikely they will face issues entering Thailand with the METV, it is advisable to have proof of onward travel and sufficient funds for the stay.
