Whilst BT is predominantly a British publication, I am surprised that there has been no mention of the fact that the Wright Amendment that restricted traffic out of Dallas Love Field will expire on Monday next week. From then on, airlines can fly anywhere from Love Field ending one of the most anti-competitive restrictions still in existence.
I only found out when I was dropping someone off at Love Field yesterday and saw the multitude of ads by Southwest airlines highlighting this. Apparently there are flights leaving at 0001 that you can book!
For those not familiar with the Wright Amendment, wikipedia gives a good summary.
