The transition away from mainframe-based systems to a Linux infrastructure represents a "major facelift for our core shopping engine" and a "huge
step" for the airline, said Steve Jarvis, Alaska Airlines' vice president of e-commerce and distribution.
The move shifts the nation's ninth-largest airline away from the system provided by Sabre Holdings to the Linux-based QPX system developed by ITA
Sabre announced a similar effort to move from IBM transaction-processing mainframes in September 2001. It said the transition would take at least
three years to complete.
