The consortium will combine its annual conference, which runs from 15 to 18 May, in Costa Mujeres, Mexico, with its ITMC Summit aimed at travel marketing companies (TMCs).
Guy Snelgar, director of global business travel, said that this move would help Advantage leverage its "global strength".
Chief executive Julia Lo Bue-Said said: “Given Advantage’s global reach, together with our ambition to deliver even greater commercial benefits for our entire network, our conference in Mexico will see us leverage our global scale and, in turn, deliver even more for those attending.
