Ah, the Howard W. Cannon Aviation Museum — because nothing says “welcome to Vegas” like a pit stop in a free airport museum! Nestled in Terminal 1, right outside security (so, yes, you can visit even if you're just killing time on a layover), this gem is packed with aviation history. Who knew Las Vegas had such a storied past with planes? Spoiler alert: they do! If you're feeling extra adventurous and want more than the displays in one spot, wander the airport. It’s like a scavenger hunt, but with old airplane parts. And hey, since it’s free, what’s there to complain about?
