The UNA pilot that was making metal bag tags with your name and plane that said "Fly Delta Jets" got a cease and desist from Legal, as did the college age dependents of active employees that made a Travelnet app where you could list with 1-2 taps on the smartphone as well as a "what are my chances" function years before we got it on legacy travelnet....IIRC the app was free so they made zero money....DL shut it down!
