It is a short flight so I do not care that much about the seats (expect if I can get an exit or something), it's more about the overall experience.
Thanks for your feedback on the lounge! Sounds tempting.
Other than the fast check-in and the lounge, TG doesn't seem to actually provide much for Star Gold members, is that correct? What is their policy to get an exit row or a row with extra legroom? There isn't much information on the forum about the seat selection on Thai.
