Hello, Based on my experience, if you’re wondering how much are delta miles worth, they typically range between 1.1 to 1.2 cents per mile when redeemed for award flights . I’ve found the best value when booking international flights in advance, especially in business class. For domestic flights, the value per mile was a bit lower, but still useful during peak travel times. Sometimes, the miles didn’t stretch as far as I hoped for last-minute trips. Still, using Delta miles helped me save money and travel more comfortably.
