I'm sorry, but I am new at this and wanted to know if I could get some help. I'm trying to redeem my dividend miles for a flight and wanted to know if the amount of miles needed to redeem award travel is determined by the cost of the ticket or by how full the flight is? Or neither? I'm trying to get a U.S. Airways round trip ticket from Philadelphia to Las Vegas in October and the amount of miles required are pretty high. If I were to pay cash for the ticket, the price would be $460.00 which is unusually high. If I were to book a ticket to LA (which is further away) the price would be $250.00 and the miles needed to redeem are lower. I'm wondering if I should hold out and hope for the ticket price to drop and then hope the miles required will drop? Or does it not work that way. Thank you for any help.
