Amazon gains UK regulator approval to expand Prime Air drone deliveries in Darlington

Amazon received a Specific Assurance and Integrity Level 4 (SAIL 4) operating authorisation and flight‑worthiness validation from the UK Civil Aviation Authority, allowing its Prime Air service to serve a larger customer base in Darlington. The approval raises the number of eligible customers from roughly 600 to about 8,000, enabling deliveries to more densely populated areas. Amazon said the milestone supports its broader plan to roll out drone deliveries across the United Kingdom and to grow its US network to almost 500 cities and towns by the close of 2026.

The regulatory clearance lets Amazon increase the scale of its UK drone trial, which could boost logistics revenue if the service proves successful. The company also indicated that the UK approval is a step toward wider roll‑outs in other UK locations and complements its planned expansion of the US drone network.
