First of all please accept my apologized to made you confused. Acttually sinces started operation at DMK, AOT can not provide the CUTE for checking in system at DMK. But BAGS can provide you the equipment(printer, computer 3 sets) and internet connection to the Carrier's system. Which is the cost 16 Baht per person.
Due to sinces started BAGS never charges for equipment ,printer and internet connection to the Carrier's system. As we have internal missed communicated. So that the reason why you have received invoice regards to these expences.
