I have an upcoming trip to Thailand and need to transfer at BKK to UTH. Last year I already gave up on Thai Smile, being they don't give *A miles anymore, and no lounge access or extra baggage allowance, even for ROP Gold members. So I normally just fly PG for domestic flights, but I want to maximize my time in UTH, being I must depart early the following morning. Checking on the TG website, there's a flight that departs 90 minutes after my international arrival, but with no special transfer immigration when heading to UTH, I'm worried if the normal immigration lines are long, and/or my incoming flight is delayed a bit, I might miss the cut-off. PG's closest flight isn't till much later, even later than the second Thai Smile flight. So I'm left with no choice but to use Thai Smile if I want to maximize my time in UTH, but they sell only tickets which are changeable with a 750 THB fee, and must be changed 8 hours prior to departure time! What kind of nonsense is that 8 hours? Do the people running Thai Smile have any experience in the airline business? Haven't they ever heard of people wanting to change their ticket at the last moment? And haven't they ever heard of people who only want to buy tickets which can be changed without a fee, even if it means paying more for the ticket? I guess I'll either buy just the earlier ticket, and take my chances, then buy a new ticket if I miss the cut-off for the first flight, or do the previously unthinkable and catch a taxi over to Don Muang and fly Nok which has many more flights than Thai Smile does. Third option would be to buy two Thai Smile tickets, one for each flight, and throw away the one I don't use. With no lounge access, miles, or other benefits, it really doesn't matter who I fly with anymore, but I just want a bit of convenience and options. I really have no idea what TG is trying to do with their Thai Smile project, but clearly it's not at all working from my standpoint.
