Stratrix’s Take

Southwest is grouped with the biggest airlines, but its revenue is under half of Delta's

Southwest sits in a club by description: "the majority of domestic airline service has been provided by Southwest and the other largest major U.S. airlines". The club is real. But a shared label can hide very different businesses, and this one does.

Southwest brought in $28.1 billion, with 2% growth and a 2% net margin. Delta brought in $63.4 billion, grew 3% and kept 8%. United reached $59.1 billion, grew 4% and kept 6%. American, at $54.6 billion, grew 1% and kept 0%. Southwest is the smallest of the four by revenue, and it sits in the middle on margin.

Outsiders use the same shorthand. Latam lists Southwest among competitors that received government support during the pandemic, next to American, Delta and United. Yet Latam, at $14.3 billion, grew 11% with a 10% net margin. The idea to repeat: Southwest shares a name with the giants, not their scale, and being grouped with them is not the same as being matched to them.
