I am looking to fly from Vientiane to Bangkok (DMK) to get a 30 day exempt entry in Thailand (I don't really fancy obtaining a Thai visa in Vientiane unless I have to and have used my two 30 day land entries already this year). Does anyone have experience of doing this? Specifically, am I likely to need an onward flight out of Thailand in order to be allowed to board my flight to Bangkok (DMK)? Thoughts appreciated!
