Does anyone have a list of what the fare codes are for Thai? I'm just checking some class availability and at first glance it appears that there's 17?? Also, is it normal for them to only show a maximum of 4 seats available on class availability? I've search many dates/times and never seen anything more than F4, A4, etc
