NJDavid: Here is a suggestion. Buy a NY-PHX-LAS ticket. You will probably get upgraded on most legs no matter you fly CO or America West. You could also play a couple rounds of Golf in PHX using the money you saved. By the way, I think most travel agencies have very little incentive to book cheaper fares for corporate clients anymore. Their commissions are fare-based and capped and the only way they can get maximum compensation is to book you on a high enough fare. Recommend your company's audit department to boost screening efforts.
