I’ll cast a vote for Wings of War/Glory. If you can find a copy, that is…. It’s also more of a beer and pretzels game, but that makes it perfect for quick pick-up games. At my local game days, I usually set it up on a side table, for people to play a quick dogfight between longer games. It takes all of two turns to figure out the rules.
There is also a 25 game , community created BoB campaign ladder on the form - it’s really good
