Just a FYI for golfers who travel: DH and DS like to bring their clubs to vaca (CA, FL, SC) so if they're not driving they fly Southwest bc SW doesn't have an added baggage fee for the club. They just travel as one of your free checked bags. If they exceed the weight limit, then you pay that added fee. Tried Ship Stix once and had a bad experience "We don't know exactly *where* your [very expensive] clubs are, sir."
