I'm sure this has been addressed elsewhere, so looking for a link that answers it. I have 38,900 forfeited miles with USAir, with a deletion date of 5/1/2009. Can they be reactivated if I book a ticket with USair? If so, what about a ticket I booked on UA, that has a CLT-PBI USAir leg. Can I change my MP number to DM number?
I know a Visa CC is the cheapest way, but I'm too lazy for doing that and not sure the 40K miles is worth that hassle.
