Regarding the TDAC card, I thought, at first, there was nothing more to do after filing the Card with Immigration, but not so in all cases. A friend recently flew to England via Air France and on his return to Thailand, Air France wanted to see a copy of the TDAC. From what he told me, Air France did not want to accept a pdf file, but wanted a copy either printed or on phone/laptop. I have yet to get all the details.
