I love southwest for their flexability and prices.
AS FOR THE LAS VEGAS CHECK IN PERSONNEL... They have repeatedly been the absolute WORST I have ever dealt with in the entire airline industry and I take an average of 20 Round Trip flights per year. I am finally taking the time to write this review after my 4th horrible experience her at the Las Vegas airport. They are rude, unprofessional, lazy, and go out of their way to make traveling more difficult for you. .. It's just so sad because they are a great airline in many other ways.
