Exactly what happened to my Buddy in late 2014 at UAal as he came off a trip he stopped by CPO office to give two week notice that he would be starting with another major based on his hometown. EWR CPO said “I’ll take your ID now them, best of luck, your done here then”. I had to give him a buddy pass to get home as he was not able to get home from base for sure. So….it happens!
