Trying to be positive post merger, there are lots more choices from SFO to CDG now (so you'd think they'd bring back SFO-CDG - since they have so many routings now...but NO!)

Anyway, I had my habits and thoughts about ORD vs. FRA vs, IAD connections on good old UA. I don't know all the new choices - and wondering if others have comments regarding aircraft, connections, upgrade chances, especially through EWR or IAH. Merci!
