“By 2025, Zipline expects to operate more flights annually than most airlines.”

Zipline hit 1 million cumulative deliveries in April 2024 and 2 million in January 2026, implying roughly 500,000–600,000 delivery flights during 2025 (the company described it as one delivery every ~60 seconds). That exceeds the annual flight count of most small and mid-size carriers, but is far below the ~1–2 million annual departures of major US airlines, and Zipline never published a direct comparison.
