This is big news: In an era of increasing fees, nickel-and-diming, and shifting frequent flier mile award charts, Delta is going the opposite direction. Retroactive to January 1, 2011, Delta SkyMiles no longer expire.
Until now, you needed to engage in some sort of activity every 24 months — either by earning or redeeming miles — in order to keep your account alive. If you didn’t, poof!, your miles disappeared.
This move is primarily a change for the better for the infrequent Delta traveler. After all, if you were a regular Delta (or SkyTeam) customer, you weren’t really worried about the expiration date, since you kept racking them up.
Rather, this helps the little guy and is bound to build up a great deal of goodwill.
