Southwest baggage allowance and fees
Every fare, including Basic, includes one free carry-on bag plus a personal item. The carry-on can be up to 24 by 16 by 10 inches including wheels and handles, with no published weight limit.
On Basic, Choice, and Choice Preferred fares, the first checked bag is $45 and the second $55, charged per direction; a third is $150 per direction. Bags over 50 pounds or 62 linear inches add surcharges: $100 (51 to 70 lbs), $200 (71 to 100 lbs), and $200 oversize.
Choice Extra and A-List Preferred members get two free checked bags. A-List members and Rapid Rewards cardholders get the first bag free, which can extend to up to eight companions on the same reservation.
Report any damaged, delayed, or missing bag at the Southwest baggage desk before you leave the airport.
Southwest fare bundles and seating
Open seating ended January 27, 2026. You now pick a seat at booking or get one assigned at check-in. Four bundles replaced the old Wanna Get Away system.
Choice Extra
Basic Basic
Renamed Wanna Get Away. Lowest price, a standard seat assigned at check-in, nonrefundable except under the 24-hour rule, and changes require a bundle upgrade. See our Southwest cancellation policy for the details.
Choice Choice
Formerly Wanna Get Away Plus. Seat selection at booking, free same-day changes, and a flight credit if you cancel.
Preferred Choice Preferred
Formerly Anytime. Preferred seats near the front and a fare refundable to your original payment.
Extra Choice Extra
Top bundle, formerly Business Select. Extra Legroom seat, two free checked bags, early boarding, free Wi-Fi, and a fare refundable to your original payment.
Three seat types: Extra Legroom (front and exit rows, up to five extra inches), Preferred (standard legroom, near front), and Standard (toward the back). Pay to pick a seat or let Southwest assign one free at check-in; a seat map shows what's open. Southwest also sells Getaways packages, gift cards, and FlexPay installments on its own site.
Wi-Fi and onboard
No seat-back screens. The entertainment portal streams free to your phone or tablet: on-demand movies, TV, live TV, music, a flight tracker, and messaging. Full Wi-Fi is free for Rapid Rewards members and $8 per device per flight otherwise (included on Choice Extra). Complimentary drinks and a snack are served on flights of 251 miles or more. There's no first or business class; the closest thing is an Extra Legroom seat.
Check-in and boarding
Check-in opens 24 hours before departure in the app or on southwest.com; with assigned seats it just gets you your boarding pass. Boarding runs in eight groups by fare, seat, and Rapid Rewards status, with Extra Legroom first. EarlyBird Check-In was retired after January 26, 2026 and replaced by paid Priority Boarding to Group 1. Families on one reservation are grouped together. Southwest suggests arriving at least two hours before a domestic departure.
Rapid Rewards and the Companion Pass
Rapid Rewards points don't expire while your account is open, with no blackout dates or caps on reward seats. Award flights track the cash fare, so points stretch furthest when fares are low.
The Companion Pass lets one person fly with you for just taxes and fees on every booking. Earn it with 135,000 qualifying points or 100 one-way flights in a calendar year; it lasts the rest of that year plus the entire next one.
Changes, cancellations, and flight status
Southwest charges no change or cancellation fees, except that Basic changes need a bundle upgrade. Choice Preferred and Choice Extra are fully refundable to your original payment; Basic and Choice issue a flight credit instead. Credits now expire: six months on Basic, twelve months on Choice. The DOT 24-hour rule allows a full refund on eligible bookings made seven-plus days out. Choice and up include free same-day changes, and same-day standby is a fare or status benefit. Check flight status by number or route in the app. See our Southwest refund policy for the breakdown by fare.
Southwest Airlines destinations and routes
Southwest flies one of the broadest domestic maps in the U.S., mostly point to point, so many trips skip the connection. Business flyers lean on corridors like Dallas to Houston, while families fill the Baltimore to Orlando run in theme-park season. The map favors places people want to go: the music of Nashville, the beaches of San Diego, the parks of Orlando. Out west, it's the rare carrier with nonstop Hawaii service to Honolulu, Kahului, Kona, and Lihue. South of the border it reaches Mexico and the Caribbean, from Cancun to Montego Bay. In 2026 Southwest added its first Alaska service, with Anchorage flights that made Alaska its 43rd state.
The most-booked city pairs:
Austin (AUS)
DAL → HOU Dallas Love Field to Houston Hobby
One of Southwest's busiest Texas shuttles with frequent daily nonstops.
MDW → DEN Chicago Midway to Denver
High-volume Midwest-to-Mountain West route from Southwest's Midway base.
LAS → LAX Las Vegas to Los Angeles
Ultra-competitive West Coast short hop and one of the cheapest corridors in the country.
BWI → MCO Baltimore to Orlando
Popular East Coast leisure route, especially during theme-park season.
PHX → SAN Phoenix to San Diego
Short Southwest hop linking two Sun Belt focus cities.
DEN → OAK Denver to Oakland
Mountain West to Bay Area route with strong Southwest frequency.
AUS Austin (AUS)
Growing Southwest focus city with nonstops across the U.S. and into Mexico.

How to find a cheaper Southwest fare
Basic is cheapest but can't change without an upgrade and earns the fewest points. If plans might shift, Choice usually wins.
Southwest concentrates flights in Dallas, Chicago Midway, Denver, Las Vegas, and Baltimore. Starting or connecting there turns up better fares and more nonstops.
Award seats track the cash price, so points go furthest on cheap fares. Book leisure routes early.
Five to eight weeks out is the domestic sweet spot, before holidays push prices up. Watch our deals page for discounts and Getaways packages.
