Maybe this is why they do not feel the need to exercise proper jumpseat etiquette and stop by the front office and ask permission to ride and show credentials. Twice last month these guys darted by the flight deck straight to their seats and never even said hello. The second time it happened the flight attendant politely asked him to come up front and see us. When he did, in a very non-confrontational way we explained that it was company policy to check the credentials of any jumpseater and it was also a common courtesy to stop by and say a quick hello to the crew. This individual acted like he knew nothing about this, all new to him, he also admitted to flying on our carrier several times before. Interesting, I even gave him the benefit of the doubt by assuming he was new and just learning the ropes. Wrong! after a check of his ID he had been there 9 months! I jumpseat on Skywest and Trans States occasionally and I always introduce myself to the FA and ask permission to see the crew. I always have ID, Medical, License in hand and ask permission to ride along. The last thing I want to do is make the pilot group I represent look bad because as it has already been stated on this thread, jumpseating in a privilege, not a right. I hope this helps anyone who might be confused on how jumpseating works.
