Marriott is pleased to announce its Preferred Travel Agency Program. It is Marriott’s goal to have every IATA/ARC/TIDS/MARTAN location enrolled in our PTA program to continue to strengthen our on – going relationship and commitment to the travel agent community. To become a Marriott Preferred Travel Agency and maintain your current commission level on the sale of Marriott commissionable products, all you have to do is to have at least one travel agent in each of your customer contact locations successfully complete the Hotel Excellence! training and exam and to sign the Preferred Travel Agency agreement.
