American Airlines and Delta Air Lines, the two largest domestic carriers in the United States by flight volume, have launched or resumed eight routes over a two-day period in early September, according to an analysis of OAG schedule data. The changes reflect ongoing adjustments in airline route networks as demand patterns evolve.
On September 3, American Eagle restarted service from New York LaGuardia to Atlanta and Madison, and began a new route from Washington Reagan National to Houston Intercontinental. The LaGuardia-Atlanta route will operate 38 times weekly using Republic E175 aircraft, while the LaGuardia-Madison link will run daily with Republic E170s/E175s. The Reagan-Houston service is scheduled for 17 weekly flights on Republic E175s.
According to the US Department of Transportation, the Washington Reagan-Houston Intercontinental airport pair saw 852 daily round-trip local passengers between April 2024 and March 2025. Including all Washington DC-area and Houston-area airports brings the total local market size to 3,496 daily passengers. United Airlines currently dominates at Houston Intercontinental with about 79% of flights. About six in ten United passengers are local travelers; the rest connect through Houston. American Eagle’s new offering is focused on capturing more of this local traffic segment.
