Should I ask her out?

Went to an alumni weekend for my sports team at college, also the girls sports team alumni weekend too.

Hit if off Friday night with this girl alumnus at the bar, see her again Saturday and we talk a little before me and my friends leave.

We end up on the same flight home in the same row, I’m in the aisle, she’s in the window across the way. We chat during boarding and then I wait after we get off and we walk together till we go our separate ways home.

She goes in for a hug as we say goodbye and follows me on IG like an hour later.

For additional context, she’s like 4 years older and dated an alumni on my team at one point, so if I go after her a bunch of my old teammates will probably know.

So do I ask her out? Is it worth it?
