Delta Air Lines SkyMiles partners are international airlines that allow customers to accrue SkyMiles reward points when they fly on these partner carriers. As of 2015, the list of SkyMiles partners includes Air France, Alitalia and Kenya Airways.
Delta groups its SkyMiles partners into four different sets according to how the partners allow customers to accumulate reward points, which customers can exchange for free or reduced-priced flights. For instance, some partners award bonus points to customers who fly in business or first class, but some partners don't offer the extra points. The first two letters of a flight number indicate which airline is the ticketing carrier.
