last minute award tikcet change possible?
Per United website, "When flying with one of our Star Alliance partners, changes must be made at least 24 hours before departure."
I am a little confused by the wording "before departure" here, does it mean that any change has to be made 24 hours before the originally scheduled departure time? Or does it mean that the new departure time has to be at least 24 hours away if flying the partner airlines?
For example, if the original departure time is 5pm with Air Canada, at 4pm (1 hour before the originally scheduled departure time), can I make the change to a same itinerary 21 days away for free, as long as the same class seat is available?
