Thinking about trying to ride NWA to London Gatwick. What are the procedures and unwritten/unspoken protocols so it goes smoothly? I know I need to show up early to intruduce myself to both the cockpit crew as well as the cabin crew. What else will score points? Do I have to clear customs with the pax or can I clear with the crew?

Is there a number I can call to be listed domestically or internationally? I ask because the gate agents always ask if I have "listed". I didn't know there was a way to list on another carrier besides FedEx's 1-800 jumpseat coordinator number. I thought you showed up, asked for and filled out a jumpseat form, which you then presented to the captain for his/her signature.

Thanks!
