F‡ MISSED TRIP PROVISION
IF A PASSENGER HOLDING CONFIRMED RESERVATIONS AND
TICKETS MISSES THE FLIGHT AND PRESENTS HIMSELF/HERSELF
AT THE UA DEPARTURE AIRPORT TICKET COUNTER AFTER THE
CLOSE OUT OF THE SCHEDULED FLIGHT AND NO LATER THAN
2 HOURS AFTER THE SCHEDULED DEPARTURE TIME THE
PASSENGER WILL BE ACCOMMODATED ON A STANDBY BASIS
ON THE NEXT AVAILABLE UA FLIGHT POSSIBLY THE NEXT

AA's rule 80 is silent on missed trips, and so are the conditions of carriage.
