Any Customer who cannot be safely accommodated in a single seat will be required to purchase an additional, non-refundable seat. You must contact the partner carrier to complete the purchase.
If you arrive at the airport and haven’t purchased an additional seat, you will be directed to contact the partner carrier to do so. If adjacent seats are not available on your Southwest flight, you’ll be rebooked on another flight with available seating.
