I'm actually surprised they aren't starting to offer UA fliers status matches.
As a 1K segment flier with the merger and US leaving *A I will have to move over and fly US in 2014 starting in January. I fly about 40% of my UA flights through US on *A and can't do 100% on UA but can do at least 90% on US if I decide to make the move (which is all but decided).
It sure would be nice if I don't have to start 2014 without status.... and really don't feel like buying up a challenge.
