That is what makes Los Angeles so fascinating right now. According to Los Angeles World Airports’ full-year 2025 carrier statistics, Delta was LAX’s largest airline with 13.92 million passengers and a 19% market share, while United ranked second with 11.87 million passengers and a 16% share. Those numbers underline how unusual LAX is: this is not a fortress hub dominated by one legacy airline, but a major airport where two of the country’s biggest network carriers are both serious contenders.
United, for its part, is clearly not backing away. The airline has continued to add flying from Los Angeles, including new service to Columbus, Pittsburgh, Kansas City, and Portland, Maine for 2026, while also maintaining a premium footprint through its Polaris Lounge and United Club presence.
At its Elevate earlier event in this month , United made plain that it sees LAX as one of the places where it still wants to climb higher. In one of the slides presented, the carrier showed a map indicating that it is the number one airline at six of its seven hub airports. The odd one out? Los Angeles. To which Patrick Quayle, United’s SVP of global networking and alliances said:
“We’re putting Delta on notice. Starting today, we will be #1 there as well.”
That is why Delta’s Florida expansion matters beyond the routes themselves. It is another move in what is becoming one of the clearest premium-network rivalries in the US market, and the only airport where Delta and United compete head-to-head in an evenly matched contest.
Delta is leaning on frequency, long-haul additions, and major terminal investment to protect and extend its lead. United is answering with fresh domestic growth and a clear message that second place at LAX is not where it wants to stay. For travelers, that likely means more flights, better lounges, and a fiercer battle for relevance at one of America’s most important hubs.
