Add IBS to the list of PSS vendors who doesn't have a client. That list includes ITA and several others.
IBS has now lost its first and only Reservations system client - Virgin America to Sabre.
I have flown Virgin many times and have heard several of the agents using the system who came form other legacy airlines and used to using a larger system curse under their breath on the tool. That said apart from some early teething problems I never was adversely affected.
So lets see what will happen when VX becomes Sabres latest player. For sure they received a SWEET HEART deal
