Your link above is to the Fare List which has been around for a while. The Fare Calendar was/is different.

The Fare Calendar allowed the user to limit the search by airline. Then, the user could see all the fares (economy, business and first) that an airline was offering between two destinations. By contrast, the Fare List pulls up only the cheapest economy fares from all airlines.

So, without the Fare Calendar, it seems that we are now limited to only seeing routing info for the cheapest economy fares unless you are flying to/from "popular" destinations as defined by Expedia. The Flight Wizard and/Fare Compare functions like the old Fare Calendar but only for listed domestic destinations. Looks like there are no fare rules available otherwise from Expedia.

The problem seems to stem from Expedia migrating to a java driven web site. Lots of pages no longer work in my Opera browser. So much for the much ballyhooed "improvements."
