SkyBonus
On November 27, 2001, Delta Air Lines launched SkyBonus, aimed toward small-to-medium businesses spending between $5,000 and $500,000 annually on air travel. Businesses can earn points toward free travel and upgrades, as well as Sky Club memberships and SkyMiles Silver Medallion status. Points are earned on paid travel based on a variety of fare amount paid, booking code, and place origin or destination. While enrolled businesses are able to earn points toward free travel, the travelling passenger is still eligible to earn SkyMiles during his or her travel.
In early 2010, Delta Air Lines merged its SkyBonus program with Northwest's similar Biz Perks program.
