If a good book is your thing, I devoured (not literally) "The Glory Years of Sir Freddie Laker" on a LHR-SFO flight back in 2019 and have just bought the sequel, "The Second Coming of Sir Freddie Laker" for an upcoming US trip. It goes into detail on a lot of the wonderful posts above, highly recommended if you like that sort of read. Hope that's OK with mods, am not advertising as I have no skin in the game. Lots of detail on keeping all those DC-10s busy in the years before 1977 and Skytrain actually happening.
