SOme of the old threads are chock full of information that if you are new to the Frequent Flyer game or need a re-fresher can help you better understand an issue.
Maybe a link would work best.
If i can remember a particular old thread I'll post the link (if others don't beat me to it.)
And personally, I love nostalga and it's fun to find some classic and very OMNI threads on here. Yes it may be ancient history to some but these threads bring back a smile to my face.
