When you are checking in online with Southwest Airlines, can someone else check in for me from their home while I am in Orlando for my return trip to STL. I read about someone doing this, but my question is - how do you handle the printing of boarding passes? When you check in online the only option that they give you is "Check In and Print All Available Boarding Passes" So if my mother -in -law checks us in ( we will be at MNSSHP), how does this work??
