I have one Chase United Mileage Plus card, which entitles me to up to two free bags on a domestic flight (though the booklet provded with card and other adds don't specify, in fine print on the website there is a restriction for up to one free bag for each of the "Primary" cardmember and a companion). i also got a second card for my wife under my card (with same CC number) and then purchase 2 pairs of tickets, one with my card and one with hers (with each of us having one child as our companion).
does anyone think i will get away with 2 checked bags for each of us (on our separate reservations) when we do computerized checkin and bag drop, or do you think it just won't work?
