The principal problem is that the government has allowed airline industry consolidation to a point where an oligopoly for air travel has formed on many routes, while smaller airlines are restricted to regional “feeder” routes only, which are not competitive threats. If the airlines were forced to compete more (i.e. broken up) then the market would take care of this sort of unfair pricing by itself. Since that is unlikely to occur, the next best alternative is to regulate the fee structure of certain types of fees and service charges that could reasonably be viewed as excess for the service provided. My preference would nevertheless be for the government to exercise its anti-trust powers more aggressively and break up the largest airlines while establishing a more equitable access system for main ports of entry and most important regional hubs.
