Mostly correct. United and Delta are great for international jumpseating. Anyone in the CASS system will get a ride, provided a seat is available in the back.

American Airlines, on the other hand, maybe maybe not. They only allow pilots from a small list of carriers to board for an international flight; off the top of my head, Delta, United, Southwest, FedEX, UPS and jetBlue. Anyone else, you're out of luck.

My understanding with jetBlue is that they were just recently added to the list only after some senior VP from American switched sides and started working for them.

If Atlas/Polar are regularly flying to your destination they are great to jumpseat on. It's a little tricky getting through their system at first, but once you figure it out easy street.

This is not true; even tough you're sitting in the back, you're still considered an ACM, and "on duty". Yes, even if you're not rated for the airplane you're sitting in. Yes, even if you don't work for the company.

What does this mean? In a nutshell, you can't drink. That's pretty much it.

As an actual "non-rev" you can kick back and enjoy your IFE with a nice glass of wine or a beer. As a "cabin seat jumpseater", you're not supposed to.

Do people do it? Yes. Will they get in trouble if they get "caught" by the flight crew? Maybe. Is it worth the risk to your jumpseat agreements for that drink? No.

Thanks guys. I knew about international jumpseat on other carrier, that's why I posted this in the cargo section.

True. I just meant that even if there is an open cockpit jumpseat, if there are no open seats in the back you aren't going. It's not that uncommon on some of the US - Europe and Europe - US flights ..

Endeavor pilot. I have jump seated to Canada on Republic. No hassle, except coming back the gate agent in Canada will charge you like 30-60 bucks (not sure exact amount). Both times I just showed up at the gate though.
