at 510 waiting on NWA, I too have mixed feelings about the value of the "free" miles here.

On the one hand, it IS free so you just click thru some stuff online and it adds up, eventually supposedly non-erroredly you get 500 mile blocks when you reach those threasholds...

On the other hand, I DO experience (and this is not always a bad thing) a bit of mile-anxiety whereas I think all these things to myself as I do such promos:

-will it work?
-will it end or change before I get the promo done?
-will there be errors and if so, who do I contact and will it be aweful like when trying to recover missing miles from the EBAY Anything Points gig with companies like Sharebuilder, or will it be easy like when you contact an airline and the CSR guy does it like right then and there and you can refresh your screen and actually SEE the error corrected? or, will it be like when you are stupid enough to actually DO one of the larger MyPoints points-earning gigs and you now actually EXPECT and find yourself WAITING ON some 20 or 100 mile posting to your long-growing account only to have to dig for the fax or phone number, send in stuff you normally would throw away and still have to wait X number of weeks to get the points only to transfer them to Hilton when you reach X thousand, only to later have Hilton one day deny you ever sent anything, which now means THEY deleted YOUR account's Hilton points and you cannot retreive MyPoints records past 6 months and depsite everything you go thru, Hilton does not accept the validity of copies of faxes of transactions to and from MyPoints and that one email in your lifetime that you did NOT save that had proof of the transfer to Hilton from Mypoints and and and...

Well, you get my point.
This one is NOT as big or bad (yet) but some FREE miles are not really worth the trouble. I tend to save things and treat every promo the same--20 miles or 200 miles or 20,000, I want 'em if I signed up for 'em. But lately I have been a bit less inclined to even want to work on GETTING the 20 mile ones or even some of the 200 mile ones...Unless it's easy 123.

If it is, I will still play. So far it's not bad but it's not great. It's just one more thing to pass the time when up late cuz the baby could not sleep.
