Do NOT fly Southwest if you have toddlers. Their boarding system is HORRIBLE for families with little kids. They let you on only after the A group has boarded and over half of the A group saves a seat or two or 6 (!@#$%&!) for their companiins in B or C group. Flight attendants not helpful, actually consdescending, whwn you are rushing to the toilet with a kid that really has to go.
