I suppose the name on your JP account and ticket will be identical. If they find, after verification, that all is in order, they normally take about a week to update the miles to your JP account.
Not having the card doesn't matter.
actually i disagree....i have managed to get my jp number attached to the reservation at check-in counter in the US for united & aa flights....they post within 4 weeks....
i always retain my boarding pass though, just in case the miles don't post & i have to send the info in to jet....
