Came from Europe last week, connected at ORD. I always ask about Channel 9 when I board and when I get anything but a "Yes", I politely inquire about asking the Captain. Overwater flight was a "Only if a passenger is specifically asking" (FA told me Captain turned it on because I asked). Domestic was a resounding "NO!" that I heard all the way back at the door. Curtains were open all the time on both flights and no announcement about "classes of service divided by curtains " was made either.
