You young pups. Delta used to fly C-130s (they were labeled L-100s in commercial use). Pictures and more info here. https://www.deltamuseum.org/exhibits/delta-history/aircraft-by-type/turbo-prop/lockheed-l-100
A handful of commercial operators still do.

Lockheed’s also preparing to offer a civil version of the “J” model for commercial use.
Thank you for calling me a young pup. I'm nearly 66 and am flattered beyond belief. ;-)
C-130?
Hell when I was a kid we landed in Ketchikan via Commercial Airlines in a PBY Catalina (used until the early 70’s)

Taint nothin new
In more recent years flown in and out of many a POS location via C-130.
When ya really can’t stand it another minute the most beautiful sight in the world is a C-130, until it lands at your destination and then you know for sure females really still do exist because ya see one and whichever one you see first just became/replaced the most beautiful sight you have ever seen.
(Still love the C-130... EX Wife, not so much)
