I don't think it is Sabre as such.
Just logged in and it was showing full functionality and direct connect access with Virgin.
To me it sounds like an overlay system such as checkin or a front end that doesn't belong to Sabre that allows you to not spend money training staff on how to operate in the "black hole" using real inputs not pull down and click boxes.
If that is the case - serves them right. Overlay systems mean that you save on 2 weeks training but wind up with a chimp that knows nothing with regards to how their request actually impacts the system they are using.
Probably not a person in sight that can drop a manual load and trim sheet either.
Oh - Brave New World
