Southwest Airlines rapped on the knuckles by DOT

Southwest Airlines (LUV -0.2%) got rapped on the knuckles again by the DOT for violating rules on fare advertising.

The carrier marketed a $59 fare from Atlanta to New York, L.A., and Chicago for routes that were already sold out.

Southwest must cough up $200K for the misdeed.

What to watch: Industry insiders think the lush profits turned up by airliners in Q1 will increase the focus on fare manipulation and misleading advertising by regulators.
