One of the few things that airlines can not enforce is "intent". They offer a seat for a price, they fly you from A to B (sometimes via C, D, E, F, and G). You pay, they fly, you sit. You can get into really complicated marketing scenarios... "the seat an MR'er bought could have been purchased by someone who could have then been loyal for years based on that good experience". Etc. But when the airlines post a $118 all-in special, one of two things is going to happen... that seat will sell, or it won't. If it sells, does it matter if it's an MR'er or someone who flies once a year?
And you can start the discussion that by buying a $118 hub->outstation, you're taking away the chance for someone to fly outstation->hub->outstation... but if the airline feels that way, then they shouldn't have offered the fare. It's simple, to me... the airlines sets the rules, we have to follow them... but we're sure going to find ways to use the rules to our advantage.
