Why would you do that?
Unless you are willing to pay for a J ticket.
I was thinking it might be a way to increase the chances of saver business being opened up, if I release the seats the day before.
In this instance I have a non-direct flight already, and I'm hoping to get saver availability on this UA flight. I figure that my chances for getting saver are better if I can guarantee that there are open seats by the day before.
I was wondering if anyone had tried this method and had success or otherwise.
The only downside would be locking up the money for that period of time.
