I understand that SWA does not charge change or cancellation fees but you do pay the difference in cost from the original flight to the new one. What I'm wondering is if changing your flight within days of departure makes for a significantly higher price. If we book one of those Wanna Get Away fares, it's relatively low priced. As we get closer to the flight, we realize it needs to be changed. How often do you find that you are having to spend significantly more for the new flight since it's so close to that date? We fly out of Dallas/Love Field which is a major hub, I think. Does being a Mid have any bearing on all this? Thanks for any info!
