Will my family be allowed entry into Thailand with less than 6-months passport validity?

Indeed Robert, thanks.

Thanks Tod for the return, I was anticipating that catch-22 situation with the air carrier... Regarding the temporary passport though, allow me to still consider it is not an irrelevant question for your group as it doesn't entail to get confirmation from one's citizenship diplomatic representation (in my case the Swiss consulate doesn't know which countries allow entry or not to travelers with temporary passports) but rather from Thai immigration policy. Some countries, like Singapore I believe, will not allow entry at all to temporary passport holders, some countries will allow if the traveler can prove he/she is in transit, en route to his/her mother land, and some countries allow entry if the passport is valid for more than 6 months. Thus, my wish to know where Thailand stands re entry in the country with temp passports.
