Just surfing and found this info,check this out and the link,it helps the layman understand the problem some.
A few airlines, including jetBlue and Southwest in the USA, have built their own hosting systems, with limited connections to the CRS's so that travel agencies can make reservations through their CRS's. Continental, US Airways, and some other airlines in the USA and abroad (notably including Virgin Atlantic) use the SHARES system run by EDS. SHARES doesn't have travel agency subscribers, only airline users, and isn't considered a CRS or regulated as one. But in many other respects SHARES resembles a CRS, and it has interfaces to all four major CRS's.
All of the big four CRS's, and EDS's SHARES hosting system, were built on IBM's IBM Transaction Processing Facility (TFP) platform. Ongoing eforts to migrate them off TFP and mainframe platforms have proven extremely difficult, slow, and expensive.
