I know and understand all that DR but perhaps if American (using the example in the article) opted to charge only $150-200 for an LAX-DFW it would negate the need for savvy DFW bound pax to bend the system by booking to AUS via DFW. Let's be honest, LAX-DFW is a prime route and the airline is cashing in by obviously overcharging. Then they bitch when some savvy pax hit back! The other option is simply not to offer AUS as an option from LAX. It's similar to say KLM quoting a high fare AMS to the USA from Amsterdam and a much lower fare from DUS. People living in between the two cities will book from DUS. On some routes it can save up to $1000 return in Business Class per passenger. I wonder if in the future KLM plan to impose a rule that Dutch residents may only depart from Amsterdam?
