I know someone much the same. He gets free flight miles, free stays and gift cards galore. Too bad he’s not smart enough to put the cards to good use like his mortgage.
My brother visited me one time and stayed at the local Marriott for free, then up to Portland, ME for free, Boston for free and Newport, RI for free. He flew roundtrip on AA for free and his rental car was free.
In that first few years of his job he visited every state except Hawaii and North Dakota. He even went to San Juan, PR once for a week.
He was a bank mortgage auditor for Fannie Mae.
