FlexPoints
FlexPoints are worth 1.5 cents each on travel purchases. With the Amex-based cards, you need to purchase your travel through the U.S. Bank travel portal. With the other cards, you can use the portal, or you can activate the card to send you text messages whenever you make a travel purchase elsewhere. You can then respond to the message to use points to offset the charges for your purchase.
There are other redemption options, but they give you less value from your points.
