Yes, I saw the inventory on LO and AC, but the UA award availability was substantial for the entire month of May until overnight on June 29th. I had my choice of C-awards on the outbound awards and had almost too many choices before purchasing. The options for the return flights also looked very good from any of several of the mentioned cities, including the MUC-ORD direct flight, even on weekends (I have to wait another week for my return flights to be entered) IMO, it's impossible for so many flights to be taken overnight, including connects in FRA, MUC, BRU and IAD. I wonder what they are up to?
