@Pablo *******

or did you mean to drop the "1", which I'd already done (I don't really consider that part of the number)

even though there is already a dropdown for the country code? So, put "001" then drop the first digit of the area code?

@Scott *******

I probably should have been clearer in my post. I will fix it now. I meant people who still have a U.S. phone number. That seems to be what's causing my problem, although I didn't try this site. Third party sites don't generally allow one to check seating availability prior to booking which is rather critical for me.

@Pete ****

sorry...five valid phone numbers, actually

@Pete ****

I'm not sure clunky explains not accepting a valid phone number (or rather four valid phone numbers).

@Mika *******

that does not solve my problem. First of all, I'm not permanently here, so there's no reason to do so. Secondly, I still need to enter an emergency contact. My emergency contact is not here. As I said, on one of my attempts, it actually accepted my number but not my daughter's. No matter what my SIM is, my daughter is still not in Thailand. I'm not sure why I need to pickup a SIM just to bypass one field on the AirAsia site when it doesn't solve my problem.

I'm not getting a seat assignment option :-(. I'm going to try one more time with an upgraded ticket (it didn't say seat assignment was part of an upgrade but it usually is).

@Cliff ********

I haven't tried that with AirAsia yet (I really hate downloading a bunch of apps). When I tried with VietJet, it was a royal cluster...ummmm...mess, shall we say. It would not even open.

@Terry *******

I just still have my U.S. phone number. After numerous tries though, it eventually took MY number, but it won't take my daughter's number and she's certainly in the States. I have no emergency contacts in Thailand.

@Terry *******

I am "here" :-). I'm in Bangkok.
