This year is Delta's 100th anniversary in the skies. In celebration, the airline's Beyond the Summer event offers SkyMiles members a slew of promotions to earn triple miles, save on vacation packages, and more. Here are the details.
Delta Beyond the Summer Event Promotions
3X miles on SIXT rentals and hotel stays
Delta SkyMiles members can earn 3X miles on SIXT car rentals and hotel stays through the Delta Cars and Stays platform. Book a car rental or hotel stay by August 20 and complete the rental or stay by November 30, 2025. Only rentals and stays booked with cash are eligible.
SkyMiles members typically earn 2X miles spent on the base rate of SIXT car rentals and hotel stays in the Delta Cars and Stays Platform. This promotion offers an additional 1X mile per dollar on eligible rentals and stays. After this promotion, rewards revert to 2X miles on rentals and stays.
The offer does not specify a minimum or maximum rental or stay length, nor does it indicate the number of rentals or stays on which you can earn triple miles. However, you should note that bonus miles through this promotion do not count toward Million Miler Status or Medallion Status.

Triple miles with $300+ in Delta Gift Card
This is another simple promotion to earn triple miles — but on the purchase of a gift card. Through August 1, purchase at least $300 in Delta Gift Cards and receive triple miles on your purchase. You can purchase multiple small gift cards, as long as the total purchase amount is $300 or more. Delta Gift Cards have no expiration date.
$300 off Delta Vacations Packages
A new Delta Vacations promotion is available for the Beyond the Summer event. Through August 1, book a vacation package with a flight and hotel stays using promo code SMSUMMER25 and save up to $300. Eligible travel is through December 31, 2025.
- $75 discount on packages $1,999-$3,999
- $125 discount on packages $4,000-$6,999
- $200 discount on packages $7,000-$9,999
- $300 discount on packages over $10,000
Eligible packages must depart from the U.S. to any Delta Vacations destination. Each package must include at least one flight operated by Delta or a partner airline, as well as a hotel stay of two nights or more. Members earn miles and Medallion Qualification Dollars (MQDs) on Delta Vacation packages.
Earn bonus MQDs on Delta Cruises
Finally, SkyMiles members can earn 1 MQD per $5 spent on cruises booked with Delta Cruises through August 22, 2025. Members also earn 2X miles on all cruises booked by the end of 2025. You can also pair these promotions with other promotions such as kids sailing free, instant savings, discounts on the second guest, and more.
Earning MQDs only applies to cruises of 21 nights or less. Earning MQDs and miles does not apply to port charges, port expenses, taxes, and travel protection. These promotions are valid for all sailings through December 31, 2026.
Our Take
Delta's Beyond the Summer event, marking the carrier's 100th anniversary, features some great promotions for SkyMiles members. Ensure you pay attention to the booking date of each promotion to earn your bonus miles, bonus MQDs, or receive your vacation package discount.
