US Transportation Department has started an investigation into possible overcharging by airlines following May 2015 Amtrak train crash in Philadelphia.
The New York-Washington Amtrak rail service was suspended after a derailment that took 11 lives and injured 200 people.
The department has sent letters to JetBlue Airways, Delta Air Lines, Southwest Airlines, American Airlines and United Continental Holdings, asking for their average fares before, during and after the accident. According to transportation Secretary Anthony Foxx, “These airlines have allegedly raised fees beyond what you would ordinarily be expected in the Northeast Corridor at a time when the Amtrak line was shut down.”
