If you know one FedEx pilot, he should be able to introduce you to other FedEx pilots. Most people come in for a "grip and grin" to meet at least a couple ACPs. Ask your friend to at least meet you in MEM and walk you through the AOC and possibly eat lunch with a couple guys. There's about 11000 applications in right now, quality recommendations (former ACPs, RCPs, respected senior pilots) definitely help.

Are there any pilots that used to work with you that are now with FedEx?

Also I'm pretty sure now your main sponsor has to have flown with you. (182s are included )

Good luck
