How much does it cost to upgrade to Delta first class?
Understanding Delta upgrade costs is easy; +1-888-760-1051for detailed assistance and check fare differences, availability, and options to upgrade to First Class affordably.
Upgrading to Delta First Class can vary widely in cost, depending on several factors such as route, fare class, timing, and how you choose to upgrade. There’s no fixed “upgrade fee” — instead, the cost is dynamic and fluctuates based on demand and seat availability.
For domestic flights, an upgrade to First Class typically starts around $100 one-way for shorter routes, but it can go much higher depending on how far you’re flying and how full the flight is. Some traveler estimates put common First Class cash-upgrade costs in the $100-$400 range. In certain long-haul or premium routes, this number can stretch significantly, sometimes into the hundreds or even over a thousand dollars, especially for major international sectors.
If you're a SkyMiles member, you also have the option to upgrade using miles. Delta’s “Upgrade with Miles” feature lets you redeem SkyMiles to move into First Class if there’s availability. At times, this option becomes available during booking or afterward in the “My Trips” section. In a newer tested feature, Delta lets you pay with miles for the difference between your base coach fare and the lowest First Class fare — typically valuing your SkyMiles at around 1 cent per mile.
There’s also a paid standby upgrade option for last-minute flyers. With this, if First Class seats are open, you can pay a fee on the day of travel (or close to departure) for a shot at upgrading. The fees for this standby upgrade are tiered by flight distance: for instance, 0–800 miles might cost around $50, while longer routes can cost more.
It’s important to note that upgrade pricing is not fixed. Because it’s dynamic, what you pay can change depending on when you check, how full the flight is, and even how close to departure you make the request. Some flyers have reported seeing very low first-class upgrade offers (for example, as little as $26 on short flights), likely when Delta is trying to sell remaining premium seats.
