I just checked SWA and the rates are down from when I booked. I booked at $706 for 4 tickets and now they are down to $626!! My question is how do I get the difference? Do I call them or can I do it online? I know that they don't refund your money but that they give you a credit right? This could be an insentive for my husband too take me on another vacation within the year. So please help!! Thank you!
