Mexicana got it as part of a deal about 1-year ago as result of the EDS plans of sunsetting the legacy Phoenix flight planning system.
I hear the migration was far from smooth, and MX already in the market looking for long term solution.
Also apparently EDS/HP is chasing after Continental to retain them also once the Phoenix goes away with promise of a new next generation Atraxis platform. Off course something like that would be a multi-year effort to redevelop the current platform.
