I was on CO.com trying to change a ticket online. After selecting a new date/flight/time it brings you to a screen that is labeled "Change Ticket Detail" which includes the the change fee and new ticket price. Below the itinerary it has an area marked "Rules and Restrictions" with several bulleted items listed with some links embedded in the text. Clicking on the links of "penalty rules" or "rules and restrictions" brings you to a very useless screen. It basically is a blank page with a back button that says "Please review the fare rules for each segment. The most restrictive set of fare rules applies to the entire itinerary." without listing any rules besides that one.

Something more intuitive on these two pages would be extremely helpful.

If it matters I was using Netscape 7.x and the itinerary was a "T" fare.
