Southwest is famously a loyal Boeing customer:
Southwest Airlines took to the skies in 1971 as a maverick upstart—and they retain this spirit today. Southwest and Boeing have been partners since the company's inception, when Boeing helped Southwest begin operations with three 737-200s. Since then, Southwest has faithfully remained an all-Boeing fleet.
"In 1971, Boeing made three white-tails available to a pissant little airline trying to start service in Texas," [CEO Jim] Parker said. "We remember those favors, and we have never flown anything but Boeing since."

Kelleher often observed that airline taxes were even higher than those on booze and cigarettes. For him he said, that was a triple whammy.
