History
Fly4 Airlines was established in August 2023 as a strategic partnership between Enter Air and TUI Group. Under the ownership structure, Enter Air holds a 51% majority stake, while TUI Group holds the remaining 49%. The airline was conceived to provide flexible capacity solutions (wet-leasing) to the TUI Group and other third-party carriers during peak demand periods.[3]
The airline received its air operator's certificate (AOC) from the Irish Aviation Authority on 5 March 2024, and commenced operations on 10 March 2024, with a fleet of four Boeing 737-800 aircraft.[4]
During its 2025 summer season, the airline significantly expanded its operations, supporting TUI Airways operations at Birmingham, East Midlands and Norwich.[5] In late 2025, Fly4 announced its first major international expansion outside of Europe, entering a winter ACMI agreement with the Indian carrier SpiceJet to base aircraft in Delhi.[6]
Operations
Unlike traditional commercial airlines, Fly4 Airlines does not sell tickets directly to consumers. Instead, it operates on behalf of other airlines using the ACMI (Aircraft, Crew, Maintenance, and Insurance), and charter airline models. While its primary launch customer was TUI Airways, it has also provided services for other European carriers, including Sundair.[7]
Destinations
Fly4 Airlines operates to various international destinations across Europe, North Africa, and Asia, depending on the requirements of its leasing partners.[7]
