Jumseating on US Carriers for CX Crew

[jumpingdoc]

Does any of you at CX based in the US uses jumpseat privileges or some sort of interline discount tickets?
How is it working out since 9/11?
Able to jumpseat easy with CX ID badge?
How do you purchase interline tickets?
How much interline tickets cost?

Looking for possible commute ATL - JFK.

Thanks mates.
