What planes do the USPS and Canada Post use to deliver airmail? If they use outside contracters, who are they and what planes do they use?

Airmail is typically delivered in the spacious bellies of your typical airliner. Surprisingly enough, airlines make a good deal of money from cargo - postal cargo included. Unless you're in the backwoods of Alaska or the Northwest Territories (and like terrain), mail is tagging along on a passenger flight as it works its way to its destination!There are bush pilots who fly mail around in the hinterlands, usually flying STOL-capable single engine planes and good rough-and-tumble airplanes built for such conditions. -Greg

USPS has contracted with Fedex for quite a while. Don't know what proportion of mail goes with them though.scott s..

I think American does some of it, too. At least, they said it in the documentary about American Airlines: A Week in the Life, anyway.
