I was on a United Airbus jumpseat a few years ago and we were talking about the automation...
The Capt speculated that one day the FO (generally speaking) would be required to occupy his seat for the take off and landing but during cruise he'd have to go back and help the flight attendants with the beverage service...
He never mentioned dogs, but man those UAL FAs...
...let's just say they're pushy, pushy, pushy.
