Dublin-based ACMI/charter specialist Fly4 Airlines (4F, Dublin International) has successfully petitioned the Irish High Court to be placed into provisional liquidation, according to Irish news provider The Currency.

A spokesperson for Interpath Advisory confirmed to ch-aviation that the court appointed restructuring specialists Brendan O’Reilly and Mark Degnan as joint provisional liquidators of Fly4 Airlines Green Limited (the company's legal name).

"The company has experienced a material deterioration in its financial position during 2026 and its current flying programme concluded at the end of October. The joint provisional liquidators' immediate priority is to take control of the company’s affairs, secure and preserve its assets, and engage with employees, aircraft lessors, regulators, creditors, maintenance providers and other relevant stakeholders," he said.

"The joint provisional liquidators will engage with the company’s airline and other counterparties regarding any operational implications."

Fly4, which operates four B737-800s with one more to be delivered, provides short-notice capacity to airlines, brokers, and tour operators, including cover for technical groundings and unexpected demand. According to ch-aviation, it dry leases three of the B737-800s and owns one.

ADS-B data shows that all four B737-800s were grounded between October 28 and November 6, 2026. Two are parked at Istanbul Atatürk, one at Nuremberg, and the fourth at Brussels National.

"We will now assess the arrangements relating to those aircraft, the company’s existing contracts, and its wider financial position as part of an orderly process designed to protect value and minimise further liabilities. We will communicate directly with affected stakeholders as the position becomes clearer," the spokesperson for Interpath Advisory said.

Fly4 Airlines was established in 2023, launched flight operations in March 2024, and is headquartered at Dublin International. It is owned 51% by Polish charter carrier Enter Air and 49% by Germany's TUI Beteiligungs GmbH. The venture was created to supply flexible capacity, particularly to TUI and other carriers during peak periods.

As reported by ch-aviation, the carrier was supplying wet leased B737-800 capacity to Enter Air in 2024 and Germany’s SundAir during October 2026.
