Passenger Statistics Interpretation
While America's record-breaking 1.1 billion passengers in 2023, a crowd primarily composed of leisure travelers casually booking on their phones, is a triumphant recovery, the conspicuous absence of business fliers and our collective sardine-like packing into a handful of major hubs reveals an industry still flying with one engine sputtering.
