[7] On 18 February 2013, in the 2013 Belgian diamond heist, eight men armed with automatic weapons and dressed in police uniforms seized 120 small parcels, containing an estimated $50 million (£32,000,000) worth of diamonds from a Helvetic Airways Fokker 100 passenger plane, loaded with passengers preparing for departure to Zürich.

The men drove two vehicles through a hole they had cut in the airport's perimeter fence to Flight LX789, which had just been loaded with diamonds from a Brink's armoured van.

[13] During a 2022 company conference, Martin Ebner, owner of the airline, discussed how Helvetic decided not to push for a contract with Swiss International Air Lines requiring the latter to pay its wet lease fees while airline fleets were grounded during the COVID-19 pandemic, losing out on millions.

In doing so, Ebner argued Helvetic helped ease Swiss' ticket refund burden during the pandemic.

They were able to afford this by relying on reduced lease rates payable to parent company, Helvetic Group, and switching to a less costly short-term temporary employment model with less hours of work for its pilots, crew and other employees (entailing less compensation).
