thank you! So I understand that when I enter thailand with passport A, I need to use the same Passport A to stamp out when I leave Thailand.
Then when I fly from Thailand to Malaysia and want to use Passport B to enter Malaysia, which passport number do I use when buying air ticket (airline require me to input passport info when check in)? I think I still need to use Passport A to check in, because the immigration counter in Thailand airport would match my passport info with the air ticket to stamp me out in Passport A. But then when the plane arrive Malaysia, if I present them the Passport B, the officer at immigration counter in Malaysia airport cannot find my stamp out record in Thailand and cannot match the air ticket (as it is having the info of Passport A), so I canβt figure out how β¦. or did I miss anything ? Wish you can shed some lights ππ»
(you may wonder why I need to enter Malaysia with Passport B, actually I can explain further but it is a bit long, so I try not to complicate it further for now, while if it is useful and necessary to tackle my query above, I am happy to explain more and also appreciate your patient for my long message, apologies in advance!)
