Also remember business have contracted fares with southwest. You could have a large travel group onnthis flight thst just booked.

ive seen this happen with other airlines on offering schedule change for vouchers trying to do this before the flight rather than a gate announcement.

They ask for a bid from PAX to change flights and then decide at the gate.
