I've never used skymiles/points before and I've had a CapitalOne card for years. I have approximately 300K points just sitting there. I'd like to book a trip to Spain this summer and was hoping to use those points. However, I'm not sure how to maximize the use of my points.
Book airfare on CapitalOne's travel portal and use the points towards payment? Generally a few dollars less expensive than Expedia.
Book airfare on Expedia and have CapitalOne apply points towards final cc bill as credit?
Book airfare directly on Iberia airlines and have CapitalOne apply points towards final cc bill as credit?
Transfer points to Iberia airlines skymiles program and use points to pay for tickets?
Not sure if it matters but Boston to Madrid in mid September 2026.
Thanks
