I don't know about monetizing, but I had this for a few years with when my mom married an airline pilot (until I got too old). I abused the heck out of it. Found places where flight schedules facilitated daytrips and would spend afternoons in NY or DC. Went somewhere for a weekend every month. Went to Europe for a summer. Dated someone in another city for a while. I became very familiar with the flight schedules for the airline. Ah, those were the days.
