The final scheduled commercial flight for Delta's 747 jumbo jet began Monday after a 24-hour delay, the Detroit News reported.

The iconic aircraft, the last Boeing 747, had been scheduled to take off Sunday from Detroit Metropolitan Airport, but the flight was canceled when Delta was unable to staff the plane with its required four pilots, the News reported.

It had been scheduled to leave Detroit Metro at 12:31 p.m. Sunday and arrive in Seoul-Incheon in South Korea at 4:30 p.m. Monday.

A company spokesman said the flight left Detroit at 7:30 a.m. Monday.

The iconic aircraft, Ship 6309, is the last Boeing 747-400 to be retired by a U.S. air carrier.

Delta had announced retiring the 747 earlier but said the plane was pressed into service for one more round trip between Detroit and Seoul-Incheon due to operational need.

The 747 will fly a handful of sports teams and ad-hoc charter flights through Dec. 31, the News reported.
