Southwest Airlines, founded in 1967, has grown into the fourth‑largest U.S. carrier by passenger volume while keeping a remarkably simple fare model. They use a single aircraft type, the Boeing 737, which cuts maintenance costs and keeps ticket prices down. Their “no‑change fee” policy also saves travelers time and money, letting them adjust plans without a penalty.
Beyond pricing, Southwest’s flexible booking and generous baggage allowance give travelers more value. The airline offers two free checked bags and no seat‑selection fee, which is rare among U.S. carriers. Additionally, their Rapid Rewards program rewards repeat flyers with points that can be redeemed for flights or upgrades, often turning a simple ticket into a long‑term savings strategy.
