Tips for booking Southwest flights
Southwest includes two free checked bags (50 lbs each) on every fare — a major savings vs. legacy carriers that charge $35+ per bag. Factor this in when comparing Southwest's base fare against other airlines.
Southwest doesn't charge change or cancellation fees. Cancelled tickets receive a 12-month travel credit (or refund for refundable fares). This makes booking early essentially risk-free.
Southwest uses open seating — boarding order determines seat choice. EarlyBird Check-In (purchased at booking) improves your boarding position and seat selection without buying Business Select.
Frequently asked questions
Does Southwest Airlines charge for checked bags?
Southwest includes two free checked bags (up to 50 lbs each) on every fare type. This is one of Southwest's biggest advantages over competitors — especially for families and longer trips.
Does Southwest assign seats?
No — Southwest uses open seating. Passengers board in groups (A, B, C) based on check-in time. EarlyBird Check-In or Business Select fare improves your boarding position for better seat choice.
What is Rapid Rewards?
Rapid Rewards is Southwest's free loyalty program. Points never expire on active accounts and can be redeemed for any available seat with no blackout dates. The Companion Pass lets a designated companion fly for free (paying taxes only).
