My business travel has been cut by 75%. I eventually cancelled all of my leisure trips other than visiting relatives. I had to cancel my Hawaii trip.
If another airline is willing to lose money hand over fist with a better schedule and better seats, I'll buy up which I've done with AA. The demand is not there for both business and leisure.
I'm also seeing disturbing signs of a general economic slowdown in the works over the past few weeks with regards to less credit available, lower pricing, and the willingness for vendors to pursue deals they would have walked away from two months ago.
