Guidelines for Customers of Size

Customers who are unable to lower both armrests (the definitive boundary between seats) and/or who compromise any portion of adjacent seating should proactively book the number of seats needed prior to travel. This purchase serves as a notification of a special seating need and allows us to process a refund of the additional seating cost after travel (provided the flight doesn’t oversell). Most importantly, it ensures that all onboard have access to safe and comfortable seating.

Booking Instructions via southwest.com

2. Select your city pair(s) and travel date(s).
3. Select the number of seats needed (“two” is the typical choice for most Customers of size).
4. Proceed through the “Select Flight” and “Itinerary and Pricing” pages.
5. Complete the “Passenger Information” name fields: For example, a Passenger named Tom Smith would designate Passenger One as “Tom Smith,” and Passenger Two as “Tom XS Smith” (first name XS and last name).
6. If a Customer purchases a Business Select or an Anytime fare, the second seat can be sold at the discounted Child’s Fare. It is important to note that the Child’s fare is available via our Reservations Sales Center only. You will need to call 800 I-FLY-SWA to book/purchase the extra seat at the Child Fare.

Checkin Instructions

1. Customers can retrieve a Security Document¹ online to pass through a security checkpoint if not checking baggage.
2. If baggage or wheelchair assistance is needed curbside, a skycap will escort the Customer to the ticket counter. The Customer of size checkin is handled at the ticket counter or at the gate (and cannot be processed online or via E-Ticket Check-In kiosk).
3. At checkin, the Customer will receive a boarding pass, Reserved Seat Document, Refund Advice Slip, and preboard directions.

¹On occasion, federally mandated procedures may prevent our ability to issue a Security Document online. Under these circumstances, please see a Southwest Customer Service Agent at the airport for assistance.
