Abu Dhabi-based Etihad Airways is prepared to invest up to €1.25 billion in Alitalia over the next four years under a possible tie-up between the two carriers, Italian Transport Minister Maurizio Lupi said.

Of that, €560 million would be used to buy new shares in the Italian airline and the rest would be invested in planes, design and training, Lupi told reporters in Rome.

Italy’s flagship carrier Alitalia, which received a €500 million government-engineered rescue package last year, risks running out of cash by August unless it can find a cash-rich partner.

A trade union source said Lupi told a meeting of Italian union representatives on Wednesday he hoped the long-awaited deal with Etihad would be completed by July 15.

Alitalia chief executive Gabriele Del Torchio said last week he was confident an agreement would be reached in a few weeks.

Rome-based Alitalia, once a national icon whose staff wore uniforms designed by Giorgio Armani, is now a symbol of economic malaise in a country struggling to emerge from recession.

The airline, which employs 14,000 people, would have to cut jobs to meet conditions set by Etihad, which already has stakes in Air Berlin and Aer Lingus.

Lupi said the two sides had discussed possible lay-offs of 2,251 Alitalia staff as a condition for Etihad’s investment, broadly in line with previous reports.
