Blocking the jumpseat will only hurt pilots on both sides of the fence, probably UAX pilots more. Most express flights become weight restricted anyhow during bad weather, so are the UAX pilots going to force their management to make the jumpseat part of the BOW? A lot of jumpseaters are left behind on a express flight due to weight, how often does that happen on a mainline flight? extremely rare. I commuted for 6 years and never had a problem with a mainline flight but when it came to express I have been left behind for weight. Should the UAL pilots ban UAX pilots from the JS anytime when there is weather and we are carrying an alternate?
