even if they don't enforce strictly, they'll always say that you need it on the phone. Things like enforcement strictness are much better asked in groups where people can share experiences.
the unfortunitely here is that the Thai law doesn't specify exactly how this works, so it leaves room for interpretation. So indeed airlines could give it their own 'flavor'. But in principle this shouldn't be different by airline of course, these aren't their rules.
Happy to read that some accept within 90 days. Stupid requirement, that no country should have. The less strict it's interpreted by anyone, the better.
not anymore, they changed the idiocy of being forced to go through agents, and they changed the name of the most idiotically named ever "visa on arrival" as well (although Thailand is also doing a great attempt for the idiocracy prize with its perfectly appropriately named visas for immigrating people).
Vietnam doesn't have visa in arrival anymore. De facto they never had it; there was a visa with the said name but unlike what it suggests, you had to apply for it in advance. They now aligned the name with the reality a few years ago, and made it so that you apply from the government directly instead of being forced to use an agent. Now, Vietnam does have visa exemption, like Thailand. But as an Australian you do not qualify.
