I am looking to re-enter Thailand for the 4th time this year. I've been pulled to side on my 3rd re-entry for not having an onward ticket ready to show at the immigration gate but was able to show it when I was pulled aside to speak with an IO. I had to fill out a form of where I was staying and a bit more info but was eventually let in. The IO stated that I should get a proper visa before my next entry or I might get denied.

Has anyone been able to re-enter more than 3 times to Thailand. I am looking to re-enter to also buy a plane ticket back to the US because it would be the cheapest and easiest route (BKK => US Airport). If I re-enter I would have an onward ticket, accommodation and funds.

Thanks for any help! I know no one here is an IO and its completely up to the IO but wanted to ask.

Edit: A bit more info, I entered 3 times in the beginning of the year with maybe 1-2 weeks or 1 month in-between each trip to Thailand (total of 98 days in Thailand this year). Now I've been away for 4 months going to Japan, Vietnam and the US.
