Here is the priority for Jumpseating on Mesaba....
Priority 1
1-FAA
2-Secret Service
3-Check Airmen
Priority 2
1-Pilots and Dispatchers on Company Business
2-Mgmt
I don't know why the rest didn't come through.. but here is the rest of what I originally tried to post..
Priority 3
XJ Pilots and dispatchers on personal travel
Priority 4
NWA, DAL, Compass, Comair, Pinnacle (not in any particular order) .. and then all other CASS approved airlines are in this priority level as well..
--There is a note that talks about Priority Privilege for NWA, DAL, Compass, Comair, Pinnacle that sounds to me like these 5 will come before all other CASS approved carriers until 30 minutes prior to departure.. after that, everyone is equal..
Hope this helps..
