Yes, you can use Delta SkyMiles to book award travel on Air France because both airlines are founding members of the SkyTeam alliance. You can search for and book these flights directly on Delta's website or app. Redemption rates are dynamic, meaning the "price" in miles fluctuates based on demand and season. In 2026, many savvy travelers also use their miles for upgrades on Air France-operated flights, though this often requires specific high-fare economy tickets. Additionally, if you have Medallion Status with Delta, your benefits—such as priority boarding, extra baggage, and lounge access (for Elite Plus members)—will carry over when flying with Air France. Note that while you can use miles for the ticket, you will still be responsible for paying government-mandated taxes and carrier-imposed surcharges in cash.
