Hello, people who know things! I'm going to Colorado next week (thanks, in part, to all of your support) and I'm flying Delta. But I have 3 flights. And there are very short layovers in between them. In your experience, am I going to lose my luggage?

It goes like this:

9:30am-11:10am flight, 12:00-12:50 flight, 2:30-3:30 flight. Sadly, the flights themselves are longer than I first thought, cause I'm crossing two time zones.

So... in your opinion, how stupid is it to check luggage and expect it not to get lost? I can pull off just a carry-on if I need to, but I'm going for 7 days and need to be ready for everything from swimming to hiking to nice dinners, so it will be a lot easier if I can check luggage! If there's, like, a 3/4 chance my luggage will be there when I arrive, I think I'll go for it.
