No, you cannot use Delta eCredits to pay for baggage fees in 2026. According to Delta’s official policy, eCredits (which are the monetary value of a previously canceled or changed ticket) can only be applied toward the base fare of a new ticket and any associated government-imposed taxes and fees. They are strictly prohibited from being used for "ancillary services," which includes checked baggage, seat upgrades, in-flight purchases, or pet fees. Similarly, Delta Gift Cards are also restricted to air transportation only and cannot cover baggage. If you want to use "non-cash" methods for your bags, the only option is to use SkyMiles, provided you are a Medallion member or have an eligible Delta SkyMiles American Express card, which allows you to check your first bag for free or pay for additional bags using miles at select airports. For 2026, travelers should plan to pay for their bags separately during the check-in process using a credit or debit card, as most Delta-serviced airports have now transitioned to a "cashless" model.
