Like i mentioned earlier. The nice or bad thing about NW was if someone changed a flight after the upgrade and under 24 hrs the FC seat would go right to R. So FC could be full with 15 plats and if a silver would checkin he would get the last FC seat even though he might have been 75 on the list to san jose or San francisco.
Made ExpertFlyer well worth the month.
Doesn't sound like V would open up with someone changed a flight within 24 hrs?
