We were hoping to book our return flight when it was cheaper. We are looking for 10/1 but I see that 9/30 has a few options that are $73 & $77 one way flights. I didn't really want to change our trip to leave 1 day sooner. On the day we want to leave SW has 17 flights still open, I assume that they may reduce flight costs just to fill them, any have any experience with this?
