The new agreement "allows management to remain focused on stability of operations and provision of services," the company said after signing the agreement on Tuesday.

The deal, valid through 2023, was signed a little over a week after a tentative deal was reached with pilots, helping the airline to avert a series of multi-day strikes that the pilots had announced for September and early October.

During that time the Trade Union of Pilots put the deal to a vote, which appears to have been successful.

Adria did not disclose the details of the deal, while Marko Kastelic, a member of the pilot union, told the STA the pilots were very satisfied with what had been achieved since work conditions would substantially improve.

Pilots had been complaining about the bad working conditions before and after the sale of this state-owned company to the German fund 4K Invest was completed in early 2016.

Since months beset by delays, flight cancellations and unannounced mergers of flights, the airline has had financial trouble for a while and is currently looking for a strategic partner.

Adding to its woes, it risks losing its operating licence due to what media reports suggest is a dismal financial state.

The Slovenian Civil Aviation Agency is expected to take a decision by the end end of October. It can either decide to let things stands as they are, it may permanently or temporarily revoke its licence, or it may issue a temporary licence.

Kastelic was hopeful the airline would be able to resolve its operational and financial problems.
