Industry Analyst View

Our analysis indicates that selecting Ontario International Airport as an alternate field provides practical operational advantages for aircraft traversing Southern California airspace. ONT offers low air traffic congestion, extensive runway lengths, and modern gate facilities.

Diverting to Ontario allows American Airlines to evaluate operational factors safely without holding over busy desert corridors. Utilizing a secondary Southern California airfield preserves crew duty limits and minimizes systemic delay cascades across the airline's Phoenix hub operations.
