Earthlink Voice is offering 25,000 Delta miles for internet phone service, a minimum commitment of six months would appear to be required to get the miles. They’re also offering 10,000 miles for using their high-speed internet.
(Hat tip to Free Frequent Flyer Miles.)
Update: Reader Alan reports that the fine print on the offer requires a 12-month commitment. So even though miles should post within six you’ll probably face a penalty for cancelling early if you want out before 12 months are up.
