Delta SkyMiles Guide
Your complete guide to maximizing credit card transfers and finding exceptional flight redemptions with one of the most valuable airline loyalty programs.
Introduction to Delta SkyMiles
Delta Air Lines' SkyMiles program is one of the most widely used frequent flyer programs in the United States. While it has a reputation for using dynamic pricing (meaning award prices can fluctuate significantly), savvy travelers who understand how to navigate the program can still find exceptional value, especially with strategic credit card point transfers and during frequent award sales.
In This Guide:
Credit Card Transfer Partners
Delta SkyMiles has a more limited set of transfer partners than some other programs, but the exceptional value of its award chart more than makes up for this limitation.
| Transfer Partner | Transfer Ratio | Transfer Time | Transfer Bonuses |
|---|---|---|---|
| American Express Membership Rewards | 1:1 | Instant | Occasional transfer bonuses of 15-30% |
| Marriott Bonvoy | 3:1 (plus 5,000 bonus miles for every 60,000 points transferred) | 1-2 days | Occasional transfer bonuses |
| Bilt Rewards | 1:1 | Up to 24 hours | Monthly 25% transfer bonus on 1st of month (1-5 minutes) |
Pro Tip: Always check for transfer bonuses before transferring points. A 20% bonus effectively makes your points worth 20% more, significantly increasing your redemption value.
