To clarify my question. I would be switching XN space to XN space both on United metal, and both Currently pricing at exactly the same amount. However at time of purchase it was 10.5k, now both the leg I have and the one I want are 19.5k both XN, what are my chances of getting an even swap done here. It is also x6 tickets, so it adds up. Any one with some insight will be greatly appreciated. Thanks.
