Just got an odd visit from the UG Fairy. I checked in RDU-SLC last night, the SLC portion was already UG'd at the window, but the four FC seats (RDU-ATL) that showed available since the window must have FCM'd and I was and had been #1 with 0 (M fare). Just got an email and got the UG... very odd, that has never happened before. Last week on the same itinerary (but a B fare), RDU-ATL cleared at window and was #1 with 7 at check in and remained #1 though boarding with 0 FC (no complimentary UGs). Just when you think you are learning the new rules, they throw a curveball.
