Delta Air Lines shopping guide: how to save more

Delta Air Lines at a glance

How saving works at Delta

Airlines do not work like most online stores. You will seldom find a sitewide promo code for Delta flights, and fares change constantly based on demand. The real savings come from four places: timing your purchase around Delta’s fare sales, joining SkyMiles and earning or spending miles, using the perks attached to the Delta SkyMiles American Express cards, and taking advantage of Delta’s flexible booking rules so you can rebook if the price drops. The details below are based on what Delta publishes on its own site as of September 2026.

Best ways to save on Delta flights

• Check the Flight Deals pages. Delta keeps a Current Flight Deals page, a SkyMiles Award Deals page and premium cabin deal pages. Deals are based on real-time availability and can disappear quickly, so book when you see a fare that works.
• Watch for flash sales. Delta runs short, limited-time flash sales. When a sale ends, the page simply says it has wrapped up, so it pays to check back or sign up for Delta emails.
• Book directly. The 24-hour risk-free cancellation and the Low Fare Commitment only apply to tickets bought on delta.com or the Fly Delta app, not through travel agencies or third-party sites.
• Use miles for award travel. SkyMiles can be redeemed for flights, and Miles + Cash lets you combine miles with a card payment when you do not have enough miles for the full fare.
• Bundle a trip. Delta Vacations packages, Delta Stays hotels and car rentals booked through Delta earn extra miles, which lowers the effective cost of your next trip.

SkyMiles rewards program

SkyMiles is free to join, and Delta states that miles do not expire. You earn miles on Delta flights (Main cabin and above), with Delta’s 20-plus airline partners, and with a long list of non-airline partners. Delta lists earning on Uber rides, Starbucks Rewards purchases, Airbnb stays, Hertz and other car rentals, Delta Stays hotels, Marriott Bonvoy and other hotel partners, SkyMiles Shopping at more than 1,000 online retailers, and SkyMiles Dining at participating restaurants. New members can enroll in the SkyMiles Starter Pack challenge to earn up to 5,000 bonus miles.

Miles can be used for flights to more than 1,000 destinations, Delta Vacations, upgrades, checked bags and other extras. Frequent flyers who reach Medallion status get perks such as complimentary upgrades, waived checked bag fees and faster mile earning.

Delta SkyMiles American Express cards

Delta’s co-branded cards are one of its biggest savings tools. Basic Card Members on the Gold, Platinum and Reserve Delta SkyMiles American Express cards (personal and business) get their first checked bag free on Delta-operated flights, and the waiver can cover up to nine people on the same reservation. Delta says this is worth up to $90 per person on a round trip. Since June 4, 2026, Basic Card Members also get a second checked bag free on domestic Delta flights. Your SkyMiles number must be in the reservation, and Additional Card Members do not get the benefit. Eligible Card Members also get a 15% discount on award travel bookings through the TakeOff 15 benefit. New cardholders can earn a welcome bonus of miles; terms apply and change over time.

Military travel benefits

Delta offers active-duty members of the US Army, Marine Corps, Navy, Air Force, Space Force and Coast Guard an expanded free checked bag allowance and early boarding. Delta also provides military medical emergency fares for service members whose immediate family member or domestic partner is war-injured and needs care. Contact Delta directly to arrange these benefits.

Price protection and the Low Fare Commitment

Delta’s Low Fare Commitment is built around its 24-hour risk-free cancellation policy. If you find a lower fare within 24 hours of booking directly with Delta, you can cancel for a full refund to your original payment method and rebook at the lower price. After 24 hours, price adjustments are not available unless you bought a refundable fare. The request must be made before your first flight departs.

Changes, cancellations and refunds

• Main Classic and above: no change or cancellation fees for travel within the US, Puerto Rico and the US Virgin Islands, or from the US and Canada to worldwide destinations.
• Basic fares: cannot be changed and are non-refundable after the risk-free period, and fees apply to cancellations.
• eCredits: when you cancel a non-refundable ticket, the remaining value is issued as an eCredit, usually valid one year from purchase.

If you think prices may fall, a Main fare costs more up front but gives you room to change plans later without a fee.

Baggage costs

As of September 2026, Delta lists the first checked bag at $45 and the second at $55 on most domestic and nearby international routes. Card Members, Medallion members and active-duty military can avoid these fees, which is often a bigger saving than any fare sale.

Sale calendar

Delta does not publish a fixed sale calendar. It runs limited-time flash sales and seasonal retail events that bundle flight deals with bonus miles on hotels, car rentals, cruises and Delta Vacations. Early access to some events has gone to Medallion Members and Delta SkyMiles American Express Card Members first. The Current Flight Deals page is the best place to see what is live.

Payment options

You can pay with major credit cards, with SkyMiles, or with Miles + Cash. Delta gift cards and eCredits can also be applied to bookings. Paying with a Delta SkyMiles American Express card earns extra miles and unlocks the bag benefits described above.

How to use a promo code or eCertificate

Delta seldom offers public promo codes. If you receive an eCertificate or promotion code directly from Delta, search for your flights on delta.com, and look for the field to add a promo code or eCertificate when you review your trip or at payment. Enter it exactly as shown and check the terms, since certificates often limit routes, dates and fare types. If the discount does not appear, confirm that the fare and travel dates you picked are covered.
