There are three primary ways to use Capital One miles for travel in 2026. The simplest method is to book through the Capital One Travel portal, where you can use miles to pay for flights, hotels, and car rentals at a flat rate of 1 cent per mile. The second, and often most flexible method, is the "Cover Your Travel Purchase" feature; this allows you to book travel anywhere (such as directly with an airline or via an OTA like Expedia) and then "wipe" the charge from your statement using miles within 90 days of the purchase. The third and most advanced method is to transfer your miles to airline and hotel partners (like Emirates, Air Canada, or Wyndham). In 2026, most transfer ratios are 1:1, and this method often yields the highest value (often over 2 cents per mile) when redeeming for international business class flights or luxury hotel stays.
