FedEx and UPS will continue to grow.
AA, CAL, DAL, NWA, US Airways will all merge and then this blob would somehow be bought by Richard Branson and the gov't lets him do it.
Skybus will have started up and failed 2 more times. Interestingly, the same pilots will all be going through these cycles, each time buying management's optimism about fleet plans and stock options.
SWA will have bought all the regionals and will buy Boeing to control the 737 market. They'll appear before congressional hearings for doing such. oh yeah, they start code sharing with Greyhound.
TSA screeners go from the blue shirt with cop badge uniforms to full airline pilot uniforms in an attempt to gain more respect. Then they demand jumpseat privileges.
Family Airlines will still be on the verge of beginning operations.
