Usually when your unable to book a reservation it's due to the connection time in most places you must have 35-45min for it to connect. The 2nd reason you may not be able to book a flight is that Southwest's system won't book a flight with multiple changes of planes it will allow a flight with say 3 stops no plane change (a direct flight) or a 2 stop 1 plane change but it won't allow 2 plane changes on a one way flight. Here's what you can do: you can book 2 one way flights or a point to point reservation (online it is called multi city reservation and can only be booked on the full website or though reservations) example of 2 one ways: SEA-BWI (on reservation 1) then BWI-ROC (on a 2nd reservation) or for a multi city reservation you could do SEA-BWI-ROC this would be on one reservation/confirmation number -Blake
