Who flies the McDonnell Douglas DC-9

Two questions in one table. Airframes is what each carrier reported owning in its US DOT fleet filing; seats flown is how much of the type it actually operated. They can rank differently, and the gap is the interesting part.

Operator
World Atlantic AirlinesWL7439.1K100.0%25.1 yr
Everts Air Cargo5V300.0%12.1 yr
Ameristar Air CargoAMQ4——33.5 yr

Airframes are the latest Form 41 filing; seats flown and share are US DOT T-100 for the type's most-flown operators — a dash means a carrier isn't among them (a freighter operator, or one that flies fewer).
