It appears that one of the simplest ways to earn Delta Skymiles may be going away. Suntrust Bank has partnered with Delta to offer the Suntrust Skymiles Debit, a nearly unique debit card that earns Skymiles on both PIN-based (Debit) and signature-based (Credit) transactions. This has been a truly fantastic way to earn miles because it means that if you were in Suntrust's business area (Alabama, Arkansas, Florida, Georgia, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, West Virginia, and Washington, D.C.) you could get a Suntrust checking account, get the Skymiles debit card for a $75 annual fee, and use the card to pay taxes, load Bluebird, or buy money orders. Essentially it has been a license to print Skymiles. For example, here's a screenshot of one monthly Skymiles statement:
A guy I know earned over 20,000 Skymiles in April.
Even with the devaluation of Skymiles, that is pretty good earning. However, it appears that this opportunity is going fast. According to Gary at View from the Wing, Suntrust seems to have pulled it's links to apply for the card. Some people are still reporting success by applying in person or by phone, however.
If you have ever considered getting this card, DO IT NOW!
Edit: The number at this LINK has been reported to work for signing up.
