Typically airlines try to encourage frequent flyer accounts to stay active by making you have some type of activity in your account within 18-24 months. I have been a long time member of Delta SkyMiles, and while I have never had an issue with having activity in my accounts to keep them active, today I received a notice from Delta stating our miles no longer expire.

The email reads:

You now can earn miles without worrying if and when they will expire as we have eliminated our mileage expiration policy – no asterisk, no fine print, no ifs, ands or buts.

We are proud to be the only major U.S. carrier without mileage expiration.

This is great news, and hopefully it puts pressure on other airlines to follow suit. The interesting piece is that Delta probably gains to lose some money with this change. I am sure Delta made a pretty penny on SkyMiles that went unused.
