Reward ticket. I think they have been having difficult conversations with people so if you can propose a solution they will be all ears. They have the power to make an empty seat into a reward class seat so not a problem if there's no award availability on your proposed new flight. But obviously this won;t work for a full flight.Was your ticket a rewards ticket or paid with cash? I'm hoping to do something similar but not sure if the fact I booked a rewards ticket will go against me.
