It would be really nice if the "Fare Basis Code" search worked with regular expressions or any other kind of fuzzy matching. Like I want to see a list of all fares starting with K for example. This isn't the same thing as all fares booking into K (the "Class Code" box) and sometimes there are too many fares to sort all of them.

Second, I don't know if this one is easy, but some time in the last couple years EF stopped showing the fare rules in some cases where my original search "departure date" doesn't match the fare seasonality. This might be an issue with de-duping fares or hitting the GDS, but I usually want to see the full table and not have to change my search just to open up different fare rules.
