Overview
SkyMiles is the frequent-flyer program of Delta Air Lines that offers points (or "miles") to passengers traveling on most fare types, as well as to consumers who utilize Delta co-branded credit cards, which accumulate towards free awards such as airline tickets, business and first-class upgrades, and luxury products. Created in 1981 as the "Delta Air Lines Frequent Flyer Program", its name was changed to SkyMiles in 1995. Originally all airlines including Delta, only gave miles for airline travel and not credit card expenditures. Delta claims to have been the first major U.S. airline without mileage expiration, so travelers can redeem awards at their leisure, but others have since followed. The airline also has a separate SkyBonus program that provides small to mid-sized business owners with a way to earn points for trips taken by employees, good towards free flights, upgrades, Medallion status and other travel awards. It has been ranked fairly highly according to some independent news outlets.
Partnerships
In addition to its Delta Connection, Delta Shuttle and SkyTeam alliance partnerships, Delta offers frequent flyer partnerships with the following airlines
Former partnerships
Royal Air Maroc was formerly a partner but joined the Oneworld airline alliance in 2020, and partnered with American Airlines AAdvantage.
Alaska Airlines was formerly a partner of SkyMiles prior to December 19, 2016.
In addition to the air miles, SkyMiles can be redeemed and even earned on SkyMiles cruises but that is actually a separate company. Miles may be used and accrued on Delta Vacations but that is also a separate company although Delta is the parent company.
