Oceanic Airlines is a fictional airline which may be used whenever a television series needs an airline. This fictional airline was popularized in Lost, but not all series that mention it are connected.

Oceanic Airlines before Lost
Oceanic Airlines on Lost
The series Lost and Alias were created by the same people and also used Oceanic Airlines, and Alias also made other references to Lost. LAX also used Oceanic Airlines with the clear intent to reference Lost. This airline was also seen in FlashForward and Once Upon a Time. Chuck mentioned Oceanic Airlines, even the flight number from Lost, but the details around the flight were inaccurate.
Other Oceanic airlines
The Oceanic Airlines on The Goldbergs "The President's Fitness Test" had a very different logo, so does not cross over with Lost.
