I hear you and it will probably be difficult to turn it around once the company has gotten authority over the jumpseat away from the Pilots. Nevertheless, you (collectively) ought to try and get it back! not only does it facilitate your own travel needs, being able to extend the privilege to a colleague who might recipricate when you're stuck somewhere, is a benefit that doesn't cost the company anything but carries a lot of value for the crewmember.
I give jumpseats to anyone that qualifies, except to those that do not recipricate and claim that the company does not allow it. I have been stuck and turned down by quite a few of my fellow airline pilots in many places, some of these folks look at you as if you are asking them for their first born.
Here goes the saying: Do onto others as you would have them do onto you!
