Under Delta’s 2026 SkyMiles rules, you cannot earn miles in your own account for flights taken by family members. Every passenger, including infants and children, must have their own individual SkyMiles account to accrue miles for their respective travel. However, in 2026, Delta has made it significantly easier to manage "Family Travel" by allowing parents to link their children’s accounts to their own for tracking. While you can't "harvest" their miles, you can use your miles to book tickets for them. A major 2026 update also allows Diamond and Platinum Medallion members to "gift" status (Silver or Gold) to family members, providing them with perks like complimentary upgrades and priority boarding even when traveling without you. If you are looking to pool points, your best 2026 strategy is to use a Delta SkyMiles American Express card, where all household spending on authorized user cards earns miles that flow directly into your primary account.
