true. But if you are thinking of changing then it’s wise to check or ask, before purchasing. If it’s the basic no change ticket then you have no option but to buy a new one.
Airlines generally have 3 levels of ticket 1 cannot change ( cheapest) 2 can change but there’s a charge 3 change no charge ( most expensive) Simple innit? Check the conditions on your ticket?
Did mine last week at the KL Thai embassy. Very helpful and well organised. Book an appointment online. Their website very useful. Step by step guide. 2 days to process. They even gave me a 3 month tourist visa chop! But I don't leave for Phuket for another 2 weeks, so will need a one month topup after arriving.
