Air miles can be a game-changer for frequent travelers, but sometimes your loved ones accumulate miles they can’t use before they expire. In such cases, how to use someone else’s airline miles becomes an important question. Fortunately, many airlines allow passengers to transfer or use miles from another person’s account, but the process varies depending on the airline. It’s essential to understand the guidelines set by the airline, as each one has its own rules for transferring miles. Some airlines may charge a fee for transferring miles, while others may have more relaxed policies. However, there are typically restrictions on who can transfer miles, how many can be transferred, and how often. To use someone else’s miles, you’ll need to follow these specific procedures, and in many cases, the person whose miles you are using will need to authorize the transfer. It’s important to consult the airline’s website or customer service to ensure you're following the correct process. So, if you’re wondering how to use someone else’s airline miles, make sure to adhere to the airline’s rules to ensure the smooth transfer and use of miles.
