I have been off and on for years, currently more on than off. Lots of good things learned along the way.
Thanks for these posts, a lot of them were great memories. I flew a lot in the early days of joining for very little. These lessons have lasted.
Changed: Mistake fares. I've come across some "mistake" fares but have kept them to my circle of friends and family. I've looked back here when I came across but not a mention.
