This program doesn't look as interesting as some of the others. The miles can't be transfered, so you must earn enough with webmiles.com before you can redeem for anything, and it looks like you actually have to buy something to earn the miles (though their press release at http://biz.yahoo.com/bw/000124/ut_webmile_1.html talks about miles for registering and taking surveys. Notice the part that says "
Many consumers have exhibited compulsive behavior in the attempt to accumulate enough miles redeemable for a ticket(s)." I object to that

If you earn 25000 miles, they promise a ticket with no blackouts, and it is a paid ticket so it will earn real miles. This program is just like the ones from many credit cards.

Still, they start you off with 500 miles just for filling out your name and address, so I figured it can't hurt to sign up. If you join, can you enter "[email protected]" as a referrer. They'll give me 100 miles per referral up to 2000 miles.
