I got one with DL miles... until AF pulled the 3 class plane...
then I had them reroute me thru LAX to get back on a 3 class.

the lady asked what was wrong with Business.... then I said it was eh. she said she could put me on DL business and I laughed... if AF biz is eh, DL biz stinks!
needless to say I had to get a different agent to actually make the desired switch.
