In 2026, United Airlines offers two primary ways to share your MileagePlus miles with others. The most high-value and modern method is Miles Pooling, which allows up to five members (a pool leader and four others) to combine their miles into a shared account for free. This is perfect for families or groups aiming for a large award redemption. Alternatively, you can perform a direct Transfer, but this is generally discouraged due to the steep cost—roughly $7.50 per 500 miles plus a $30 processing fee. For the best value, most travelers simply book an award flight for someone else directly from their own account. This incurs no transfer fees and only requires the recipient's name and travel details. While pooling is excellent for group goals, remember that miles contributed to a pool cannot be taken back if you leave, remaining in the shared pot for the remaining members to use on United-operated flights.
