Two years of intentional credit card spending paid for every single flight. Here's the exact stack we used.
Two years before we left for Europe, we started a spreadsheet.
It tracked every credit card point, every transfer bonus, every sweet spot on every airline's award chart. It was, by any reasonable measure, too much. Our friends thought we were obsessive. We were obsessive.
It paid for every single flight of our European summer. Four round-trip business class tickets to Prague. Positioning flights across the continent. The flight home from Athens.
Total cash cost: $0.
Here's exactly how we did it.
