American Airlines adds Boston-Buffalo route while cutting Miami-Sacramento service

Industry analysts have noted the competitive environment in Boston between Delta and JetBlue, making American's entry into this market notable. Previously, American and JetBlue had cooperated through the Northeast Alliance in Boston and New York from 2021 until 2023, coordinating schedules and offering reciprocal loyalty benefits. That alliance ended following antitrust concerns, leading both airlines back into competition.

According to data from the Department of Transportation analyzed by Cirium, JetBlue carried an average of 183 passengers per day on this route at an average fare of $178.

In addition to expanding in Boston, American Airlines is reducing service elsewhere. The carrier will discontinue its Miami-Sacramento flight after January 5, 2026. This route was launched in December 2023 as part of a broader domestic expansion from Miami but did not meet expectations for profitability. However, American will continue Sacramento flights from other cities including Charlotte, Dallas-Fort Worth, Los Angeles, and Phoenix.
