US DM Membership card (not Preferred)
I signed up for DM at the end of last year, but have still not received my membership card. All I really want to use it for is to check in at the airport, since usually I don't have the credit card I used to book (my parents').
Does US issue regular DM cards? Do they have a barcode or strip on the back for checking in? I know for example, Airtran does.
Thanks
