There are probably other airlines out there, but I’ve listed the major ones here.
By the way, Continental Airlines is omitted this time because its livery is almost the same as United Airlines’.
Maybe don’t add political/controversial planes or liveries into the game. It’s a game about being an ATC at a public airport and flying imaginary people to destinations.
I only really see Air Force One being a special plane, even then, WOA hasn’t added Russian planes/liveries due to the war, so they would surely not add Trump’s 757 for the same reason.
727 sounds like it would only come with Kai Tak, trump never operated anywhere remotely near there. Wouldn’t be added any other way because of the stupid “no defunct liveries” rule
