I never received this survey and I fly Southwest specifically because I found their boarding process to be less of a hassle (for a single traveler who doesn’t care where they sit). The only way I could see this being beneficial is if they board people in order of assigned seat in such a way as to optimize time to seat, not the BS boarding that other airlines do to try and maximize price of fair, otherwise they will have lost the whole reason I like(d) to fly them… Their simplier, no bs, boarding process.
P.S. I really don’t get people liking to pidgen hole themselves to a specific spot for any of these things, just makes it easier to inflate the prices later
That and a rotating menu likely adds overhead costs as it prevents you from specializing (skills, equipment, and ingredients acquisition)
