I am a leisure traveler who has flexibility on departure and return dates and flight times. When searching for a flight I will usually check a few dates around my desired date to see if there's a better price or itinerary or departure time for my destination. One of the quirks of the Southwest website is that every time I go to a different date the sort basis reverts to a default sort of "Stops" and I have to remember to change it to my desired basis. I find this incredibly annoying and don't understand why the sort doesn't just stay on the basis I selected for that session. It would seem to be an easy change for SWA to make.
