I purchased a flight from Narathiwat (NAW) to Bangkok Don Muang (DMK) on 7th of November 2011.
Having a confirmed booking, which can still be seen as confirmed in their web page (today, 1st of November 2011), our flight in not scheduled any more, so it will be probably canceled.
We haven´t got any information from them and they even don´t reply to emails, only automatic responses.
So we don´t know if we will fly or not, but probably not.
Safety was terrible....
no response to email sent to them...
will not fly again
Escort for unaccompanied minors: Some low cost airlines offer escort services for unaccompanied minors - usually aged more than 6 - for a 50 EURO fee per flight. Children are entrusted to a specially trained adult who deals with the border crossing formalities, takes care of the children during the flight and safely delivers them to the person waiting for them at the end of the journey. Obviously, it is not possible for under-age children to travel on indirect lowcost flights, because it is not the escort's job to check children in for the onward flight. However, the escort will collect children's luggage after a direct flight. In order to know what the requirements for minors to travel alone are, inquire with the Border Police.
