SkyMiles is Delta's frequent-flier program. Members earn miles by flying with Delta and doing business with Delta's partners, which include other airlines, hotels and car rental companies, among others. Once they accumulate sufficient frequent flyer miles, members can redeem them for upgrades to first- or business-class tickets or for other types of award travel on Delta and some SkyTeam partners.
Buy an economy class ticket on Delta, Northwest, or a participating SkyTeam partner airline.
Check how many miles you need for an upgrade on Delta's upgrade award chart: http://www.delta.com/skymiles/use_miles/award_upgrade_mileage/delta_upgrade_awards/index.jsp#5.
Call Delta SkyMiles at 800-323-2323 to request your upgrade.
Request an upgrade at a Delta ticket office or an airport ticket counter in person if you don't want to call.
Have your Delta SkyMiles PIN and a credit card handy. You also will need a valid ID if redeeming your miles in person.
