I agree, Smitty. Brother and his wife save Delta points. Period.
I told them about how they could get more points, or even cash back, by either going through the Delta shopping portal, or other, cash back portals. Their eyes were glazing over.
And he's an MD, and she's got a degree, as well. They fly business, maybe, every three or four years, and go to Europe at least twice a year. It's what makes them feel good, so, it works for them.
I LIKE the knowledge that, by working a little harder, I can fly J or F, whenever I want to, and stay at quirky hotels for the cost of the time it takes me to MS on a 2% or 5% card.
