Since CO and UA miles will/can be merged, I figured I would try the CO Mileathon scheme and get some bonus miles. But I've not had the best of experience with this promotion so far. First of all, it is really hard to find a link from your account page on CO.com and I always have to do a Google search to find the page. And even then, it is March 22nd and I still get the: Thank you for registering for Mileathon. Check back often to learn more about credit-earning activities. It feels like this promotion is not on the up and up, cause I don't understand why they wouldn't post more uptodate/accurate activity information. Is this how CO usually runs their promotions?
