Delta is going big in Los Angeles. By summer 2027, the airline and its partners plan to run more than 200 departures a day from LAX to nearly 70 destinations — the largest schedule in its history at the airport — and it's backing up the volume with new routes and heavier frequencies across the country.

Two cities are joining the map. Twice-daily flights to Monterey, California start December 19, 2026 on Delta Connection Embraer E175s, handy for anyone heading to the Monterey Peninsula, Carmel or Big Sur without the drive up the coast. Then from June 7, 2027, Delta launches daily Philadelphia service on an Airbus A321neo — a pointed move into American Airlines' turf on a transcontinental route United couldn't sustain.

The real story for travellers is frequency, though. From spring through July 2027, Delta is boosting a string of domestic routes: Raleigh-Durham up to two daily (April 12), Boston to five daily (May 6), San Diego to five daily (June 7), then Cincinnati, Houston and San Antonio to two or three daily each from July 11. Seattle gets the biggest lift, jumping to eight flights a day. For a market like LA, where most passengers are locals rather than connectors, more flights per day means more flexibility if a meeting runs late or a plan changes.

Delta is also leaning hard into the premium end. Its $2.3 billion Sky Way project linked Terminals 2 and 3, and Delta One passengers get dedicated check-in, private security and two Delta One Lounges. By 2028 the airline expects four lounges in those terminals — over 60,000 square feet and more than 1,000 seats combined — plus a new 11,000-square-foot Sky Club in Terminal 2 arriving in 2027. Lie-flat Delta One is already available on select domestic routes, including New York, Boston, Atlanta, Honolulu, Maui and Kona, and long-haul flights increasingly use A350-900s with 40 Delta One suites.

Internationally, the airline now flies to Sydney, Brisbane, Melbourne, Auckland, Hong Kong and Shanghai from LAX, with Manila launching next March — 25 international destinations in total, with partner one-stop access to over 100 countries.

None of this means Delta owns LA. United remains strong across the Pacific and just announced new Osaka service; American has a broad domestic network and will grow once its own gate project wraps; Alaska owns plenty of West Coast loyalty and Southwest matters for California hops. But with more flights, seats and premium seats than any rival at LAX in summer 2027, Delta currently has the strongest case for the crown — and the competition keeps fares honest for everyone.

If you're booking domestic or Pacific flights out of Los Angeles in 2027, this expansion is worth watching: better schedules, newer aircraft and more lounge space all work in your favour.
