As a fan of shopping portals to earn extra points/miles I've always been disappointed that there was no way to earn extra points/miles for Amazon purchases. Last year United's Mileage Plus X smart phone app started offering miles for the instant purchase of Amazon Gift cards. At one time the rate was as much as 3 miles per dollar. Now the current rate is 1/2 mile per dollar. Download the Mileage Plus X app to earn extra United miles.
JetBlue and Amazon have recently teamed up to offer JetBlue Customers 3 Miles per Dollar when using a special link. Here is a link to the the JetBlue Amazon offer: https://trueblue.jetblue.com/web/trueblue/amazon
Even if your not a frequent flyer of JetBlue their points never expire and they you can pool your points with other family members. So go ahead and grab some free points/miles with your Amazon purchases!
