Between the high cost of jet fuel and regular challenges facing a notoriously expensive industry, multiple smaller and charter airlines have faced financial challenges to the point of having to shut down over the last few months.
Launched in 1988 out of a general and charter airport in the affluent Lisbon coastal suburb of Cascais, Portuguese charter airline OMNI Aviação provided both chartered private jet flights to its wealthy residents and general aviation services such as air ambulance transfers to the local municipality.
In September 2026, the airline entered insolvency proceedings in Portuguese court and subsequently had its air operator’s certificate (AOC) suspended by the local aviation authority due to an unviable financial situation.

The AOC is the regulatory approval that a commercial airline needs to run flights and sell tickets to passengers; while without it an airline is unable to legally get off the ground, the license can either be temporarily suspended or permanently revoked.
According to the latest reporting from Swiss aviation news outlet ch-aviation, OMNI Aviação has now had its AOC permanently revoked by the Autoridade Nacional de Aviação Civil (ANAC).

While few details around the details of the case are publicly available (OMNI Aviaçao could not be immediately reached for comment on its situation), this looks to be the final page for an airline that was at one point one of the most recognized private jet operators in Portugal.
The airline had previously requested a temporary AOC suspension from ANAC; it is unclear what ultimately led to the permanent revocation.
