Pilots are protesting over the firm's plan to expand Transavia because they fear it will drive down their wages.
It's hard to argue otherwise.
Air France's european business has been strongly hit by the low-cost carriers competition—as it's the case with other legacy carriers across the continent.
I remember a discussion I had with some AF staff a few years ago. The plan was clear: Air France would become a premium product to compete on long-haul (and selected shorter routes) and the rest of the company would become low cost.
Honestly, I don't see how the company can healthly survive otherwise—no matter how hard it must be for the existing staff.
