Found this chart put out by Southwest Airlines interesting - not sure what "Other Select Fees" means... I've always liked their free bags policy and no charge to change your flight ... Seeing some cheap fares popping up randomly that weren't there yesterday so keep an eye out if you're pricing flights.
