Circadian Aviation (GAJ, Bridgeport Igor Sikorsky Memorial) has phased out the sole Part 135-certified Global-series jet it operated since 2023, a Global 5000, ch-aviation research reveals.

The 15.5-year-old ultra-long-range jet, now registered in Mexico as XA-RFB (msn 9372), was previously based at Stuart Witham. It was last active as N776SV on March 13, 2025, flying between Houston Hobby and Monterrey Mariano Escobedo with a stop at Laredo. Five days later, it was exported to Mexico, where it is now privately operated.

In 2023, Airshare acquired both Circadian Aviation and Sterling Aviation and now utilises their respective Part 135 certificates for charter operations. Airshare’s own certificate continues to include a Global 5000, while Sterling Aviation's includes a Global 6000.

Across the three certificates, the combined charter fleet comprises 84 jets manufactured by Bombardier Business Aircraft, Dassault Aviation, Embraer Executive Jets, Gulfstream Aerospace, Hawker Beechcraft, Textron Aviation, and Pilatus Aircraft, distributed as 46 under Airshare, 20 with Circadian Aviation, and 18 operated by Sterling Aviation.
