If your ticket already includes this PSC, likely (but not absolutely) on tickets purchased ~ Nov 2006 and later, then no worries. If your ticket was purchased earlier then be preapred to pay the 700 THB at check-in.
Just wondering, is there any way to know if the departure tax has been included by just looking at the ticket?
