Also the in the fine print, the primary(basic) card holder must be traveling. You are not the primary(basic) cardholder if your Skymiles number is not printed on the card. Also check that the Skymiles # on the PNR is the same # that is on the card. Had a problem with the free bag because Amex assigned me a new Skymiles # when I applied for the card ( even though I provided my Skymiles #) and the two numbers did to match. Had to call after trip and have the two Skymiles accounts combined.
