I just checked the route to West Palm I fly and they're only offering the Basic and the Extra; the Plus which I generally fly is gone, meaning on a whole they've made this route more expensive.

Edit: did some pricing. The Basic now works out to about the same as the Plus after paying extra for the bag I suppose, but now if I have to change I lose the fare as opposed to being able to change for a fee. Still getting less for the same amount.
