I’m flying USAirways next weekend and was a bit apprehensive, because that’s supposedly when the airline cuts over from Sabre to Shares (and more specifically, to the America West implemention of Shares called Qik).

A Customer Service Director for a USAirways call center details some of the difficulties that the switchover is going to cause in a thread on Flyertalk.

It looks like the transition may be delayed because of a data error compromising the privacy of some frequent flyer members. It doesn’t appear to be a widespread problem, but it’s changed the priorities for their programmers.

”We’ve got our entire development team, which is supposed to be working hard on migrating our systems, pulled off and working on this,” Danziger said Friday. “And they are hoping they will have a solution to make an emergency change tonight — otherwise over the weekend or Monday.”
