<<Sharing with the competition won't happen in our lifetimes - besides which it is probably illegal....US airlines are wary of the trust busters....>> I'm aware of the internal firewalls. Market share and ARC data is currently available to all carriers who want to pay for it. Right now, AA knows what % of lift UA gets in whichever markets they choose to target, and from which ticketing sources. All they need to do is agree to hand the data off to a third party. And PNR information sharing is a hot topic, particularly in Europe. I believe Amadeus found itself in The Hague on just this point several months ago. --------------------------------- Do You Yahoo!?
