Yes, it was April 1. But the new April issue of Hemispheres appeared to be the CO one (as I observed on a connecting flight). Bev menu referenced only CO, with their obnoxious extra charge for specialty cocktails in First Class. It was a big inconvenience for FAs and pax on UA 847, SFO to IAD. A single menu was shared with interested pax, a PA announcement was made, but sales must have been down considerably.
