Basic Economy holds less potential for Southwest Airlines than it does for major carriers, at least while they lack pre-assigned seating.
The value in basic economy is less the $20 each way buy up they might charge leisure travelers, and more the way it is used to segment business travelers to keep them buying higher fares.
In order to get value out of basic economy Southwest would have to assign such customers the last boarding position, so that basic economy customers get the worst seats, otherwise there’ll be little reason not to buy the fares and pay for more expensive fares instead.
