MOON TOWNSHIP, Pa. – Southwest Airlines is cutting its route between Pittsburgh and Los Angeles, Pittsburgh International Airport announced on Monday. Service between the two cities, which had been operating six days a week, was suspended in June due to issues with the airline’s Boeing 737 Max 8 jets. There have been problems with the plane — two 737 Max 8 jets have crashed under similar circumstances since October 2018 — and that has led to the Federal Aviation Administration grounding all 737 Max 8s.
