Frequent flyers are often well-aware of the value of air miles and the perks that come with them. However, there are times when accumulated miles go unused before they expire, leaving those miles to go to waste. If you’re wondering how to use someone else’s airline miles, you’re not alone. Fortunately, most airlines offer the possibility of transferring or using miles from another person’s account, though there are specific rules that must be followed. These guidelines can vary widely between airlines, so it’s crucial to understand the process before you attempt to use someone else’s miles. Some airlines, for example, may allow transfers only between family members, while others may have more flexible rules. In some cases, transferring miles may incur a fee or require that both parties be part of a specific frequent flyer program. Additionally, it’s important to note that transferred miles may have an expiration date or specific terms for how they can be redeemed. To avoid any issues, make sure you carefully review the airline’s policies on how to use someone else’s airline miles before initiating the transfer.
