Kind of a clunky implementation of transparent pricing that the feds are pushing.
Oddest thing to me is that the "Premium" level of tickets includes NO checked bag. Then the "Business" level includes 2. None of these four fare levels includes just one bag.
edit: doing a dummy booking, I see that you can add additional baggage like the old interface. I also see that as a Diamond, the usual stuff is still $0. We now get 2 checked bags even selecting the lowest "Basic" fare.
