As someone with 26+ years at Fedex, and a commuter, I can assure you, you will fly lots of night, hub turns or otherwise. I'm doing domestic day stuff currently and still can't avoid beginning or end of trip night turns, if for no other reason than to position to work or get home at the end of a trip. To avoid nights is next to impossible and your schedule will be totally controlled by your focus to avoid nights. If nights are a big issue with you, Avoid any freight operation, Fedex or otherwise. Its the nature of the business.
