I'm flying to Thailand today from UK, I was advised by travel agent to complete the online visa exemption form/landing info, the sent the link in their travel info which I did with some difficulty (country of origin is required in 3 different places on the form and the UK is not easy to find on the list as it's GB on one, United kingdom in another, very confusing.. anyway all done on Sunday.. but now I'm seeing this isn't even a thing until May 1st, so was that just a waste of my time?
