Delta Aims for Largest-Ever Los Angeles Schedule with New Routes and Frequency Boosts

Delta Air Lines disclosed a three-route expansion centered on Los Angeles International Airport (LAX). Effective December 19 2026, the carrier launched twice-daily nonstop service from LAX to Monterey, California, and daily nonstop service from Salt Lake City to Monterey, both operated by SkyWest Airlines with Embraer E175 aircraft. A daily nonstop flight from LAX to Philadelphia International Airport will commence on June 7 2027 using an Airbus A321neo. In addition, Delta will add one extra daily round-trip on seven existing LAX routes—including Boston, Cincinnati, Houston, Raleigh, San Antonio, San Diego and Seattle—phased between April and July 2027. The combined changes are projected to push Delta’s peak-day departures at LAX past 200, serving nearly 70 destinations by the summer of 2027.

The expansion follows a year of aggressive growth for Delta’s Southern California hub. Since the previous winter, the airline introduced long-haul services to Hong Kong, Melbourne and Manila, and it will restore LAX-Vancouver service in November after an eight-year hiatus. The Monterey additions revive markets last served from Los Angeles in 1999 and from Salt Lake City in 2008, extending Delta’s California coverage.

Public sources agree that Delta will exceed 200 daily departures, but the exact peak figure (e.g., 210 vs. 215) is not disclosed. Additionally, while Delta projects a daily LAX-Philadelphia flight, no carrier-wide frequency comparison with American’s six-to-eight daily flights is provided beyond the statement that Delta’s service “won’t come close” to matching that frequency.
