Yes, you can — I actually booked a Delta flight from Atlanta to Los Angeles using my Air France Flying Blue miles last year. Since Delta and Air France are SkyTeam partners, you can use one program’s miles on the other airline, though the availability and value can vary. I tried figuring it out online but kept running into confusing error messages, so I called 877-764-3622. The rep explained my options, helped me find a Delta-operated flight I could book with Flying Blue, and even compared it to what the cost would be if I used Delta SkyMiles instead. It was super helpful and saved me hours of guesswork. Later, when I needed to adjust the return leg, I used the same number to modify my ticket. Honestly, if you need to instantly book, cancel, or modify Air France or Delta flights, that’s the fastest way.
