Overview
- Federal officials confirmed an investigation into the Dec. 18 incident at George Bush Intercontinental Airport involving Volaris Flight 4321 and United Express Flight 4814.
- The FAA says the Volaris A320neo turned right after takeoff instead of the assigned left turn, placing it on the ERJ‑145’s departure path from a parallel runway.
- Both crews received TCAS Resolution Advisories and executed evasive maneuvers before continuing to their destinations without injuries or delays, according to FlightAware and local reports.
- Replay analysis indicates the conflict peaked around 1,200–1,300 feet shortly after liftoff, with aviation commentators highlighting the risk of non‑intuitive ‘long way around’ vectors that exceed 180 degrees.
- Tower audio reviewed by analysts shows the United Express crew reporting an RA as the controller initially replied “stand by,” while CommuteAir says its crew followed ATC instructions and Volaris has not commented.
