Mine too is a pre-merger CO booking (reward, if that matters). It shows a US confirmation number, but the odd thing is there was never any US flight involved. The itinerary is CLE-EWR-FCO-EWR-CLE. When I look up the confirmation number on US's website, it's valid alright but, oddly again, it shows our flights as "cancelled," when they are not (thankfully) on UA's website. Still, why is there a US confirmation number at all on an itinerary that has no US flights?
