I hated seeing that in the office. GA guys jumpseating to DFW to do their recurrent training.
Ask if they are Jumpseat qualified. They need to do 3 levels of "training". Ask to see their 8430-13. These are given out by the office to authorize jumpseat. If they have a beard/ goatee. NOPE!!! And if they give you crap, ask who their FLM is, and a number to reach that FLM to discuss... (FLM=Front Line Manager= their boss).
