The removal of the 51-mile grace window has left me pretty bummed. I do DFW-STL (550 miles) a lot. I hate going there, but at least it was a good use of a sticker, and as a PLT, I normally cleared. Now it costs 2 stickers per leg, which just isn't worth it. 10 trips to STL will earn me 4 stickers. If I upgraded all segments, it used to cost 20, but now will cost 40?! I know all flights 500 miles or less will be complementary now, but I'm on those pretty rarely, and it's usually some little RJ that isn't worth upgrading anyway. It's a pretty hard jump to go from "complementary" to "2 stickers"...
I guess I need to push for EXP this year to make STL not suck so much.
