Google it. I found an article that said faa insider says cargo airlines may operate under new rules or old rules, their choice.

But now I found this off fox:
Cargo carriers like Federal Express and United Parcel Service, which do much of their flying at night, would be especially affected by the new rules. The same holds true for charter airlines that transport nearly 90 percent of U.S. troops and about half of the military cargo around world. They've urged the administration to allow them to operate under different rules than scheduled airlines, warning that some military missions could be jeopardized.

NTSB Chairman Deborah Hersman has said the industry's argument isn't credible. They can still fly the same missions, Hersman told The Associated Press earlier this year, but they may have to add extra pilots to their crews and make sure pilots have places onboard or on the ground where they can get sufficient rest before flying again.

So who knows....
