Chris Beitsch. Yes. Out of the country. There's a couple of ways of doing it. You can buy a cheap ticket and just forfeit it, or buy a fully flex ticket and get a full refund (don't use Thai airways, as they're only giving credits at the moment). Alternatively you can buy a phantom ticket where you pay for an apparent booking which doesn't actually take place, but you get a written confirmation of a flight.
What visa are you looking at? If you're tourist it's easier not to bother with visa. Just arrive on visa-exempt basis and you will be stamped in for 45 days, with the option to extend a further 30 days. As there's no visa, you won't have to send your passport anywhere, and you can apply for the COE online, once you have flight, accommodation and insurance arranged
