Aviator Red (converted from Old USAirways Card). Have held card since 2014 and use it regularly. Annual fee posted end of Dec.
Received offer to waive HALF the annual fee (so, half of $89), which I thought was odd. Asked if they could fully waive, but they said no.
Also had an offer for 5,000 miles after $1K spend.
Haven't accepted either yet. Will call back in a week and see if I can get the full fee waived.
