Sounds like I will have some competition haha. Been doing it for about 8 months now. I have never seen it be weight restricted even with every seat taken. The only times I've had an issue are when for fog or whatever reason the flight gets canceled the night before and the 6am flight gets canceled as well. Its happened twice to me. So make sure you check on that before going to the airport. And of course you can always jump on the airport express and go through SFO or OAK. They offer a 50 percent discount to crew if you buy your ticket online if you choose to go that route. Also I've seen other jump seaters a few times, mostly American guys but most of the time its been open for me.
