FAA officials say the two planes "landed safely after experiencing a loss of required separation" as they were headed to Sky Harbor.

The Federal Aviation Administration is investigating after a United Airlines flight and a Delta Airlines flight had a near-collision over Phoenix on Saturday.

Multiple airlines are being affected by the delays including DELTA, American Airlines, Southwest, and a few others.

The two flights, United Airlines Flight 1724 and Delta Air Lines Flight 1070 came too close to each other while arriving at the airport.
