Ascend Airways


Ascend Airways formerly Synergy Aviation, is a British ACMI and charter airline headquartered in Bishop's Stortford, United Kingdom. It is a subsidiary of the Avia Solutions Group, the world's largest ACMI provider. The airline specializes in providing wet-lease capacity for other UK-based airlines, tour operators, and government departments.

History

The airline's origins date back to 2004, when it was founded as Synergy Aviation. Initially operating as a small-scale charter and management firm, it was acquired by the Dublin-based Avia Solutions Group in July 2023 to serve as their primary UK-based operator.
Following its acquisition by Avia Solutions Group, the company was officially rebranded as Ascend Airways. In April 2024, the airline secured its Type A Operating Licence and route licence from the UK CAA, allowing it to operate aircraft with more than 20 seats. Its inaugural commercial flight took place on 26 April 2024, operating from London Southend Airport on behalf of Chapman Freeborn.
In 2025, the airline significantly expanded its fleet and international presence. On 3 November 2025, it was reported that a sister carrier, Ascend Airways Malaysia, was launched to provide similar ACMI services in Southeast Asia.

Operations

Ascend Airways primarily operates on behalf of other carriers during peak seasons or to cover maintenance gaps. Notable long-term partnerships have included:
  • TUI Airways: Wet-lease operations out of London Gatwick during the summer 2025 season.
  • Oman Air: A wet-lease agreement announced in December 2025 to support the Middle Eastern carrier's network.
  • Air Sierra Leone: Providing operational capacity for the newly launched West African flag carrier.
