Southwest Airlines has experienced great success through effective employee and customer communications. It began service in 1971 with three Texas cities and has grown to over 550 aircraft serving 72 cities. Southwest focuses on building teamwork among employees and prioritizing customer service through initiatives like casual dress policies, profit-sharing, and transparent internal communications. These efforts have helped Southwest maintain profitability while others struggled and achieve best-in-class metrics for on-time performance, customer satisfaction, and baggage handling.
