From 1982 to 1985, a company called United Air Carriers flew as a US airline under the names Overseas National Airways and then National Airlines. This airline was the second user of both names after the original Overseas National Airways and National Airlines (1934–1980). The airline was started by former officers of, but was not a legal successor to, the original Overseas National Airways ("original ONA").

The parent company of United Air Carriers operated commercial aircraft outside the United States starting in 1977. While these were commercial aircraft operations by a US company, they were not performed under a United States airline certificate and were thus not those of a US airline.

The history of this carrier is confused by multiple uses of the same name for different entities. Apart from the original ONA, the airline used the name "Overseas National Airways" at least twice for different entities and also used the name "United Air Carriers" at least twice for different entities.

The combined entities controlled over 30 large commercial aircraft at its height.
