In my jumpseat experience on NW, I've had to remind the gate agents EVERY TIME that they can now take 2. Once I even had to grab a NW pilot to prove it for me. Usually when they figure it out I get a "oh yeah" or some half hearted excuse. It's like they know but don't want to let us have it. According to the same agents, all jumpseaters now get "random" searches too (it's not really random if everyone gets one is it?), so be ready to get harassed by the agents if you jump Northwest.
