Although I have never missed my SW flights I have come very close several times. I am just wondering, suppose my flight departs at 9am and I arrive at the airport at 9:15am, i have already printed my boarding pass, the 9am flight has already departed (lax-sfo), can I take the 10am flight (assuming seats are available) at no additional cost? or will SW charge me a fee for missing my earlier flight?
thanks
