US Airways Dividend Miles (Pre-FlightFund Merger) - 20% Off future flight - why not US?

Just about every airline now is offering a "buy a ticket, get 20% off a future one" deal on either Orbitz or Expedia. I think it was started by AA, promptly matched by most majors, and now even AS and Midway are in on the deal. Not so for US! Their absence is quite obvious.... but why?
