We are traveling in August as well, and i should have booked SW when the airfare first came out, but I thought $129 each way was a but high....silly me!! It has gotten soo high, and anything out of JFK or LGA is not any cheaper. So we have decided to take the Auto train. Drive to Lorton, VA (just outside of DC) and take the train and the car. Much cheaper than flying and we will not have to rent a car. I am still hoping that airfare will drop, but for now looking forward to something new to us Train Travel!!
