Is it a problem to return to Thailand with a passport that has less than six months of validity?

The user, a Canadian expat living in Thailand on a Retirement non-O visa, is concerned about returning to Thailand with a passport that will have less than six months of validity upon their return. While there is a general rule requiring six months of validity for entering Thailand, responses indicate that the airline's policies may be more critical than immigration's. Some users suggest renewing the passport in Bangkok before traveling, while others share experiences of traveling with less than six months of validity without issues. There are also suggestions to contact the embassy regarding potentially obtaining an emergency travel document.
