In order to sit up front on NWA you must either be a NWA pilot or approved employee, a pilot for a WHOLEY owned subsidiary, or a pilot for a code-share partner. This is straight from the memo a NWA pilot showed me back in November when they instituted the new policies. Otherwise, they will/can take two off-line jumpseaters plus as many on-line people as there are jumpseats including the FA jumpseat. This makes a total of 4 or more per airplane and I have yet to be bumped by these guys. I wish all majors would re-write their own rules to make it easier for off-line guys to catch a ride. If you don't want to make it "open" seating, at least try something like this - we're talking about un-sold seats here.
