I have quite a few unused tickets both E and paper. Do these guys expire? Should I somehow get paper tickets issued for the E-Tickets that I have or should I be OK?

I once ran acrossed a very friendly United agent who went through their system with a comb to find any unused tickets that I might have. She said that they didn't usually do it and even had to switch phones so she wouldn't get in trouble.

After that, I called USScare to see if they could do the same. Well, one of the rudest people I've ever dealt with (regardless of industry) refused to even try to find anything.

So, does anyone have any ideas on how I might also be able to determine if I have any unused tickets that I may have forgotten about? I am premier on both United and USScare and those are the only two airlines I am really worried about. I also belong to both of their lounge programs.

Any help is appreciated...would be nice if I could search somehow myself.
