Strange... I had my flight on hold and tried to purchase it (before 11:59PM), and got this:

The price of this itinerary has changed since you selected your flight(s).
This happens because seat availability often changes based on demand for a particular flight.

The lowest available total price, including taxes and fees, is now:


Fare: 599.20 USD

I know it's supposed to be 24 hr hold w/ guaranteed fare, so what's up with that? There are 2 pax on my itinerary.

EDIT: I just got off the phone w/ AA, apparently I was off by an hour! Doh!
