We automatically track qualifying flights when your SkyMiles account number appears in the reservation record. That's why it's important to give your SkyMiles number when you're booking your reservation, and to use your name exactly as it appears on your membership card.

Fill out the form on the Request Mileage Credit page. Be sure to include flight number, dates of travel and ticket number. See Mileage Credit Rules & Conditions for more details.

Go to Forgot SkyMiles Number for everything you need to know about retrieving lost or forgotten account numbers.

If the name and address is exactly the same on both accounts, contact Delta Reservation Sales and request account consolidation. If the accounts have different names or addresses, the best thing to do is send a written request that includes the member's signature and both SkyMiles membership numbers to SkyMiles Account Support. Note that only the applicable mileage credit (and not any duplicate enrollment bonus) can be transferred to the remaining account.

Your miles will stay active even if you don't purchase a flight or have any other account activity – the miles currently in your account and those earned in the future are yours to keep regardless of account activity. However, we do ask that you maintain current contact information in your records with us. We reserve the right to close dormant accounts if you do not respond to our efforts to confirm that your account is still active.

Customers have told us they value their miles. With this change, we now are the only major U.S. carrier without mileage expiration, so customers can fly with us and use miles with confidence on their terms and timeframe. In short, this is great for our customers. Additionally, it helps us keep valued customers active and engaged with the airline and the SkyMiles program.

These changes will better reward SkyMiles customers who predominantly fly on Delta-marketed flights.

MQMs earned for partner-marketed flights vary by carrier.  See delta.com/partnerairlines for MQM earn details for each partner.

The marketing carrier is identified by the two-letter code before the flight number.  For example, “DL 55” signifies Delta flight 55 and “AF 200” signifies Air France flight 200.

A fare class will begin with a letter such as L, U, T, etc. and will usually be the first letter of the “Fare Code” or “Fare Basis Code.” An example of a booking class may be (L) and the fare basis code may be “LE7NR”. On a Delta ticket, you will find your booking class under the header “Flight and Cabin (Class)” and is located in the Trip Summary section after selecting your flights or under the “Fare Rules” section. Other websites may have this information under “Fare Rules and Restrictions” or “Fare Terms and Conditions” and can be located on the website prior to purchasing your ticket.

The MQM earn changes will go into effect for Delta-marketed flights booked on or after March 1, 2013, and for partner-marketed flights flown on or after March 1, 2013.
