The airline went from being the *least* enshittified airline in America to the *most*. Southwest is now worse than Spirit airlines - no, really. Southwest doesn't just merely charge for seat selection...
Obviously, passengers who are given middle seats (and the passengers around them, who paid for window or aisle seats) don't like this, so they try to change seats. So SWA now makes its flight attendants order passengers not to switch seats, and they've resorted to making up nonsense about "weight balancing":
