We are not elite---by flying AS "a lot" I meant that it is the only domestic airline we fly. But we fly short West coast routes and do not accrue enough miles for elite status.
So should I be concerned? I still have time within the 24-hour period to change to a different flight (if there is one with seats). It would be a less convenient flight so not a change I want to make if this situation is nothing to cause concern.
On the other hand, we would rather make that change now than get bumped at the airport.
