"Is this now the new frontier airlines???" said one Southwest flyer on X.

Southwest Airlines replaced open seating with assigned seats after more than 50 years.

Starting Tuesday​, customers on Southwest flights will have assigned seats.

For a large person, each flight on Southwest was a game of roulette under the airline's longtime unassigned seating policy.

Some customers have dubbed the Southwest Airlines policy "garbage," while others were more impressed with the shift.

The carrier has claimed that its customers prefer the new policy, despite some pushback.
