Re: My Points in general. I have found that I have to "keep on them" about the points. I keep a little spiral notebook by the computer and everyday I write the date and what I did on the My Points site. Then when the credit appears in my account I draw a line through that entry in my notebook. I go back once every week or two and send them an email about the one's that they didn't credit me for.
Yes, it's a royal pain in the fannie, but I'm addicted to the miles.
Oh, and a lot of the sites state that the points won't be credited immediately. Some say as long as three weeks, but most, such as the more.com site say 7 days. That's not too long to wait for 3,500 miles per week just for saving myself shopping trips.
