I agree with you. Which is ehy I'm relieved that UA does NOT participate in the Amex Plstinum program (which costs $300 o join but alllows members to buy 2 for 1 Business/First Class tickets on a bunch of airlines).

Its hard enough to compete for premium seat inventory against fellow FFers, but those airlines that allow Amex Platinum members, further exacerbate scarce inventory and thse folks have NO alllegiance to the airline..
