Is it really the same subject though? I feel like it was my mistake to start by saying I would be switching from DL, but the question still applies to any frequent intl flyer on a competing airline/alliance. My question is specifically directed at how the challenge works, and NOT necessarily at reasons why I would switch.
I hope that made a little more sense. If my questions still don't merit a different thread, then that's fine. I just wanted to make sure my intentions are understood
