Like has been said before, the j/s on the 737 is very nice indeed. I sad in the jumpseat on a few occasions with Royal Airlines in the 737-200, and it was great. Not the most comfortable, but hey, the view is unmatched. Good luck. Westjet is an easy going company, so you as an employee might get access. With Canada 3000, even as a flight attendant, we weren't allowed to sit in the jumpseat.
