UA seems to have updated my existing reservation that has the ORD-DEN segment. In the iOS app, it shows Snack now, instead of Breakfast.

Still not sure if I'll cancel and switch to my AA Award reservation (it gets a "continental/snack breakfast). Right now, I'm hedging my bets on weather (ORD/DEN in January if there's a storm...) vs. my ALB-DFW-GJT flight on AA. The lie-flats on ORD-DEN seem nice (plus since I booked so late with AA, I'm in bulkhead for the ALB-DFW segment and a CRJ700 from DFW-GJT).
