copy pasted from United's site. Doesnt say anywhere that it must be booked with United. From these terms it seems that as long as the FFN & taxes are paid with the CC & entered on the reservation you can get a checked bag. If someone actually flew using LH or SQ miles & got a free bag please advise.
