Thread: visa exempt entry to bkk

Hi I am hoping to fly to Bkk on a one world sublo par of cx staff with BA, due to work commitments i can only travel close to xmas, i was looking at the 23rd and 24th as the chances look good on flight stats compared to other dates, does anyone have a better idea than me as to what the chances would be for those dates? , also i was going to get a visa exempt entry of 30 days on arrival, but in order for BA to allow boarding without a visa i would need an air ticket out within 30 days of entry. Would BA accept another ticket booking the same as the one i am travelling on (dated to comply with the 30 day rule)?
many thanks
