Gentleman, Captain Tony is very likely correct. This isn't his first rodeo. Catboat sailor too.

Some who are observing out that some of the interview "failures" are nonsensical (failures who are LCA and Chief Pilots, PROMOTED AFTER, the failure) need to understand that Endeavor needs qualified Captains, Line Check Airmen and Pilot-Managers. If Delta hires all the qualified folks from Endeavor, who's left to manage, mentor and fly for Endeavor?

With other subsidiaries Delta has been known to stop hiring from the partner to avoid a staffing crisis at the affiliate. Just a consideration.
