So, a little recap on the Northwest Airlines situation: Northwest announced Tuesday that it will begin charging people a fee for buying tickets basically anywhere except their website or Orbitz. To fight back, Sabre, the technology that lets many travel agents book tickets, said they would bury Northwest’s flights so agents would find it difficult to book them. Now, Northwest is pissed: they are suing Sabre for breach of contract. In short, buy your NW tickets from their website. Other carriers are watching this closely and, I suspect, will follow suit in due course.
