Current situation with UA as of 01:30 EST....

Weather impact

"While we do not expect weather to interfere with the cutover process, we expect rain to turn into snow Friday evening around ORD. Therefore, we canceled 65 United Express and 12 mainline segments to minimize "creeping delays" that could extend operations past the start of the quiet period."

Time for me to get some shut eye before flying home....good luck to all tomorrow....
