I recently searched for a flight to europe that i could apply a SWU to upgrade from economy to business. on AA.com i found a flight JFK-CDG that showed that a systemwide upgrade was available. clicking on the systemwide available it the new window showed available from coach to business from JFK to CDG. i put the itinerary on hold and called American to verify availability before completing the booking. the agent said that just because it showed on the website that it was available it did not mean for immediate redemption...only to be put on the waiting list. is this the way this is supposed to work?
