Read the FOM. " Insignia commensurate with their present bid award."
Awarded FE= 3 NOT 4 stripes.
If your over 60 and still flying as an FE wearing 4 stripes you failed retirement. Wearing 4 stripes tells eveyone about your insecurity and lack of self esteem. OOOH look at me " I used to be important" or " I dont mind pouring coffee and doing the preflight in the rain. " But I obvoulsy have a problem with this percieved lesser job.
