US Airways Dividend Miles (Pre-FlightFund Merger) - What happened to PSA miles when USAIR took over

I recently found several thousand miles from PSA in my files - Did they get wiped out?

You are testing my memory but I recall that my PSA FF number was converted by USAir with an additional digit appended on each end. (My 7 digit PSA number xxxxxxx became a 9 digit axxxxxxxb USAir number.) I believe the miles were transferred and for some period of time, USAir had a 10,000 mile R/T award on the former PSA routes.

Methinks your miles were transferred but I wouldn't bet the house on it.
