If you were given the option to do your online check in and get your boarding pass you can head straight to the boarding gate, I do this all the time with Air asia
according to chatgpt money spent using your foreign card via card payments or cash withdrawals is not considered as remitted since it doesn't get to circulate into the Thai banking system therefore not due to tax. I wonder how they could track this flow of funds anyway
if one doesn't have a Thai bank account, is money transferred into your wise or revolut account considered money remitted to Thailand therefore taxable?
