Long Beach International Airport — Long Beach, United States

A restored 1941 Streamline Moderne terminal building gives LGB one of the more distinctive passenger experiences among American airports, its curved lines and murals recalling the golden age of air travel even as modern gates have been added alongside it. Long Beach's aviation roots run deep: Douglas Aircraft Company built airliners and military planes at the adjacent site for decades, a legacy later carried on by McDonnell Douglas and Boeing, whose C-17 transport program operated nearby until production ended in the 2010s. Strict noise regulations, born from decades of community pushback, cap the number of daily commercial flight slots, which has kept LGB smaller and quieter than the sprawling airports elsewhere in the Los Angeles basin. JetBlue built a significant West Coast presence there, drawn by its convenient location for southeastern Los Angeles and Orange County travelers who prefer to avoid LAX's congestion.
