Federal regulators are raising scrutiny of Southwest Airlines after a series of troubling incidents

Southwest Airlines is under increased scrutiny by federal safety officials. The move comes after a series of recent incidents including planes flying too low over water and taking off from a closed runway. The Federal Aviation Administration said Tuesday it has increased its oversight of Dallas-based Southwest. Twice within recent weeks, Southwest jets have flown unusually low while still several miles away from airports where they intended to land. The FAA declined to provide details, but noted that it continually adjusts oversight of airlines based on risk. The FAA appears to be reacting to concern about airline safety since an unused exit blew off a Boeing 737 Max during an Alaska Airlines flight in January.
