I thought it was a bit strange that the two policemen trying to break up the fight used only one arm each while the other held their radios ? Eben the girl in the white dress kept hold of her phone in one hand. Perhaps "Stun Gunns" would be more useful in the hand than the radio ?
I have been using Thai Driving licence for ID purposes when flying domestically here for the past 10 years without any problems.
I use Nok, Air Asia. and Thai Lion Air, and travel on average once a week.
Best approach to this issue is contact your CC company who were the payers. I am sure they will fix the issue but mine only allow 1 month from transaction date until you notify them. Visa Card have always refunded my account in these situations.
