Yes, they do! I remember flying to El Paso, Texas, for a work meeting, and Southwest was actually the easiest choice. The best part wasn’t even the fare—it was how simple it was to modify my flight when my meeting ended earlier than planned. I just opened the manage-trip page, tapped change, and grabbed an earlier option. It took less than two minutes. That’s honestly the best way to book or edit anything with Southwest—instant changes and no change fees make it painless.
