Depends. Does your carrier have a reciprocal agreement with the airlines you are thinking of riding on? And for the most part, CASS has NOTHING to do with Int'l JS'ing.

Also, AA and CAL have domestic JS lists, and International JS lists. YOUR company may be on the domestic list, but not on AA or CAL's international list. If so, no ride for you. It's always the CA's discretion, but if he goes by the rules he is given and you don't get on, dems da rules and you are SOL. If he lets you on, hey, you scored.

As far as I know, DAL, USAir, and UAL don't have seperate dom/int'l lists. Don't know about NW.

Depending on where you want to go, consider Polar, Atlas, Gemini, or Kalitta.
