Depends on what's in your carry-on. They don't have acid stores (yet, well maybe in Portland) so I'll be damned if my ten sheets are getting checked and stolen. Or my take-daily-or-die meds. Or my laptop that would be a huge clusterfuck to restore from backup.

Imagine flying in 1 day for a wedding and they lose your checked bag with the bridesmaid dress or fitted suit. Happens all the time.

So yeah, although stores do exist, I'm standing as soon as possible because I want to make sure not to cause myself extreme extended stress due to lost luggage.
