Zipline

“Zipline plans to conduct high-volume flight tests this year [2023] involving more than 10,000 test flights using about 100 P2 aircraft, with first customer deployment to follow.”

Zipline has never published a 2023-specific P2 test-flight count; by November 2025 it cited more than 150,000 physical P2 test flights in the US, but the first commercial P2 delivery did not occur until January 2025, well after the 'shortly after' timeline implied in 2023.

“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.

“Zipline completed more deliveries in 2022 than in all previous years combined, and is planning to complete about 1 million deliveries by the end of 2023.”

Zipline announced its one-millionth commercial delivery on April 19, 2024 — roughly four months after the end-of-2023 target it had set.
