As someone who doesn't sit in the front of the plane and doesn't necessarily get a chance to ask the captain for Ch 9, is it ok to accost the captain at the gate before the flight to ask if they'd be willing to turn channel 9 on during the flight? There are a lot of flight attendants that don't even know what it is (made even more complicated by the fact that it's no long actually channel 9 on 77W).
