If you are flying AA 1445 ORD-LAX this afternoon, it has been replaced by special segment flight 9265 (same dep/arr), but with a 762 instead of a 757. If you are in F already, you might want to snag one of the few seats left in the 1st cabin. If you are upgrading and haven't cleared, you'll have very good odds today since 40 seats are being sold as F.
