Check 21
 

Did I overlook this topic being discussed?
I've heard daily flights of bank work won't continue to be flown due to some political deal called check 21.
That doesn't sound good for a lot of time building jobs.

Check 21 is the new electronic check clearing system. In the near future banks will be able to scan checks into their system and transmit them electronically thereby eliminating the need of using priority air couriers.
Ameriflight, founded by transporting checks has recongnized this technology and is now diversifying into other field of service to maintain profitability.
I wouldn't worry about it too much, those time building jobs will still be there for you. You'll just be transporting other things.

Most of the nation's private, local banks have stated that they won't be able to impliment the required changes in the time the fed had originially stated. Therefore, the check21 legislation has been changed multiple times to allow the result is that while being reduced, there will still be some flying around for this purpose for quite a while.

AirNet, and others have also diversified and are doing a pretty good job finding new contracts. UPS, and Fed Ex are always changing feeder contracts and I know quite a few have changed hands recently. If you're looking for an hour-building job this option should be around for a few years. The big problem, however, is that they're switching from barons to caravans so your multi time just went "poof".

There were plenty of people telling you that Check21 was going to remove all freight jobs, but last I looked they couldn't hire fast enough.

So much for aviation experts.
