Buying miles allows you to accumulate frequent flyer miles without having to travel. This can be a great way to save money on flights, especially if you travel frequently. There are a number of ways to buy miles, including through credit card rewards programs, airline loyalty programs, and third-party brokers.
One of the most popular ways to buy miles is through credit card rewards programs. Many credit cards offer rewards points that can be redeemed for miles. The number of miles you earn per dollar spent varies depending on the credit card, but some cards offer very generous rewards rates. For example, the Chase Sapphire Reserve card offers 3x points per dollar spent on travel and dining, and these points can be redeemed for miles at a rate of 1:1.
