My guess is that the carry on policy varies from airline to airline and even plane to plane within an airline depending on the size and type of the plane. Different airports may even enforce their own policies as you attempt to get through their TSA screening.
I'd at least call the airline in advance to see what their policy is and perhaps print out a copy of it to take with you in case a gate agent should happen to challenge you.
When should you serve and volley in doubles? Only when you want to win.
