Same. I would use miles for any travel opportunity that I can. Usually my planning doesn't permit their use, but I'd burn them if I could. They're not liquid, unlike the cash you'd spend on a ticket instead. And they don't appreciate like an investment.
The only reason to "save" them is if at 95k miles she's a few short of where she'd really like to go, but needs say 100k for the flight.
(And for a more frequent flier, saving some miles for upgrades is worth it of course).
