Overnight LAX flight traffic has been a little noisier than usual for residents of Playa del Rey and adjacent Westchester neighborhoods.

Aircraft at LAX have been making westbound departures and arriving from the west between midnight and 4 a.m. as part of Federal Aviation Administration flight check operations to ensure the airport’s instrument landing system is working properly, LAX spokesman Marshall Lowe said.

The good news is it’s almost over. The changes started Monday and end Friday, Dec. 18.

On the flip side, aircraft will be arriving and departing from the airport’s east side from 6:30 to 8:30 a.m. one day this week, possibly Friday, in order to test air traffic flow.
