After comparing your links, I see that there are a few parameters that your ticketing platform added to the end of the URLs, like ReturnURL and CntPageID. You can go into your Google and Bing Webmaster Tools, and Yahoo Site Explorer as well, and tell these search engines to ignore those parameters on all URLs of your site. I'd also recommend canonical URLs if you have the option in your ticketing system. Now I'm not sure whether or not those parameter handling settings will be sent to SEOmoz when linking to Google WMT. Anybody?

Looks like you are having dynamic page canonicalization i.e duplicate pages are generated dynamically.

You can set the rel=canonical tags to solve the duplicate content issue.

As Daniel mentioned below it is still not clear on how these pages are being generated and linked.

Your question does not make any sense. How do you remove a duplicate page? Delete it. If it is being caused by some backend issues, then use the rel=canonical tag to specify the original page or 301 redirect the duplicates to the original if you can do that.

In your example I'm not sure what you are asking. The URL's are cut off in your question as well as on my browser, are these examples of two different URL's showing an identical page? Are you saying there is an internal link somewhere that points to the wrong place, and it is returning a duplicate of the original page or something? Then change the internal link to point to the right place.
