I'm going to be new to this privelage and wanted to ask a few questions. I know a girl down in Colombia and the only US airline that goes to the the city she lives in is American. What is their policy towards non AA/AE pilots as far as jumpseating to south america?

I have grandparents in Germany that want me to come see them soon. UAL doesn't do any flights to Germany (that I'm aware of), and it's handeled by Lufthansa. May I jumpseat on Lufthansa to Germany even though it might be a "UAL" flight? How does jumpseating work with Code-share foreign airlines? Hopefully this makes sense.

These are all pending the Gate agent, head flight attendant, and Captain will allow me to do so. Which I plan to ask for each of their permission.
