Over the past months we’ve seen many airlines impose bag fees. I’ve been holding my breath, waiting for some politician to say it just isn’t “fair” and use the power of government to force airlines to stop. That’s just the political environment we’re living in right now. But this Business Week story illustrates the beauty of the marketplace to sort things out. Consumers are making buying decisions and, based on recent passenger traffic figures, they’re rewarding two airlines that don’t impose the fees. In other words, consumers are expressing their displeasure with price and are backing it up with their wallets. This is the natural behavior that no government official or program can ever accurately predict. Bottom line: let the market work.
