[QUOTE=CJ1120;15502922(2) are planning to migrate to the StarNet system once the next release is available[/QUOTE]

"StarNet" is not a reservations sytem. It is essentially a hub that allows the Star Alliance partners to connect with each other. You may be thinking about the Altea platform by Amadeus. This is a reservations and departaure control system by Amadeus that many Star carriers use.

UA has had a long running project to covert to Altea for the last 7 years that was essentially cancled a couple of years ago.

UA will eventualy have to covert to next generation HP/Sabre/or Amadeus solution but i doubt that has been decided what the long term choice will be.
