Since you can't combine this promo with others, I'm not sure there is any reason why you would sign up now (in case a better promo comes along), but I thougt I would post for those interested.

Can I earn double miles on a September flight I've already booked?

Interesting. Good to see them trying to lessen the September drop off as much as they can.

Any word on whether this gets you double EQMs or just redeemable miles?

I don't know for sure, but since the fine print says, "Offer cannot be combined with other mileage promotions", I assume the answer is just double redeemable miles, regardless of the fare class purchased.

Yes. The fine print says, "This promotion is open to all EarlyReturns members who register for the promotion prior to qualifying flight activity."

I'm getting an invalid promo code error, I just type I'm DBLER for the promo code, do I need to do something else? Thanks.

You've got the right promo code, so I don't know what the problem would be.

Hate to suggest it, but maybe telephone the call center for help. But, I'd wait until after this fall sale as the call center seems to be more swamped than normal.

I just successfully signed up from this link:

You were logged in and the site had not logged you out, right?

That worked, Thank You!

Glad it worked! So far I have six August flights planned and not a single September one, but that might change...

Bump.
