Check with Southwest however...
I believe you have to have the photo id of each of the passengers when you check in with the sky cap (to get your boarding pass). I don't know if you physically have to be present, but if you do, they may have to wait for you to catch up with them before actually checking in...
We did this on our outbound trip in Providence (hubby dropped me and the kids off with the luggage while he parked the car in the garage.) I however assumed he had to be present at check in so we waited for him to walk over from the garage before we got in line.
