that must have to do with the new 60 day visa-free. So I will do a border run after 60 days. Simple. I will buy a border run ticket when I get there then. 26K Baht for a spare flight sounds like BS to me. So when it is 30 day visa free you buy a ticket out of country all I do is walk from my condo to the immi. Office.
I never been there with a visa and stay 90 days. Its a matter of reporting to Thai immigration or its Laos border to get another 30 day stamp. Pro Tip. -Cash is required-
