After reading the comments, I began to harbor second thoughts about trying to fake my way on the plane. The US Embassy was letting me go there on a walk-in basis since mine was an emergency case, but then I got a email that all appointments were canceled due to a possible mass protest. Then I hit upon a plan that I was surprised wasn’t mentioned here. That is to leave a day earlier.
I was considering buying a new, one-way ticket to Bangkok and worrying about any refund later. But it turns out you can “change” your flight on the website. I’ve never had to make a voluntary flight change before so didn’t know this could be done online. The website walks you through the process step-by-step. The advantages of doing this is that you can keep the same booking number with all the history of payments etc and any refunds are automatically credited to the new payment. The extra cost of changing the return leg of my trip was almost the same as what I paid for the original roundtrip ticket!
I hoped that since moving my passport expiration one day out on the AirAsia website allowed me to continue check-in, bringing my flight date one day up would also allow me to check in, but couldn’t be sure about that until I tried checking in. And it worked. I was able to get my boarding pass.
At the airport, I bypassed the counter and proceeded directly to immigration. At the departure waiting room, no one checked my credentials like before. Upon boarding, a ground staff used a handheld device to scan your boarding pass. Seems like any red flag shows up on the scanner. He asked the older farang guy in front of me how long he was going to be in Bangkok. When the man said he was staying overnight and flying home the next day, the staff let him go through to the plane.
So I passed the first hurdle – leaving Indonesia. The second was entering Thailand. I would have to be scrutinized by immigration at Don Mueang, which is notorious for giving those with multiple visits a hard time. And this was going to be my 4th VE this year. Surprisingly, absolutely no questions asked. I breezed through my second hurdle.
What I didn’t know was that I had inadvertently created a new hurdle. By returning to Bangkok a day early, I had extended my planned 30-day VE stay to 31 days.
