It is so amazingly simple to create a script that can bring back the fares of your competitors and do an analysis of your fares versus theirs. You can have all of this placed into an Excel sheet that shows where there are differences so that someone in revenue management can see where their fares aren't competitive and adjust accordingly.

Either they really do sell those more expensive flights, so they don't care to do this, although I don't know who is buying them then. Or they really just are that inept at IT and revenue management and just don't care.
