There hasnt been any USAS checkin in the QF network for years now. USAS checkin changed to the Qube dcs system from memory the Easter weekend after the Taarsan/Qantam cutover to Qube. I agree that Taarsan was just the easiest most logical system to use and its a great shame its still not around. However if losing some SYDOOL availability for a couple of days is the most major thing that has happened since Amadeus then I would call that very successful given the potential for things to go wrong in such a large project.
