U.S. Probes Possible Airline Price Gouging of Four Airlines

The U.S. Transportation Department on Friday began an investigation of possible price gouging by four American airlines in the aftermath of a deadly Amtrak crash in Philadelphia in May.

Transportation Secretary Anthony Foxx said the investigation would focus on the practices of Delta, American, Southwest and Jet Blue in the Northeast corridor.

The Justice Department said earlier this month it is investigating whether the airlines worked together illegally to keep air fares high by signaling plans to limit flights after the rail crash.
