Brussels Airlines has a huge problem with keeping experienced pilots. The older and more experienced pilots have gone to other companies where there is a better salary and more attractive conditions. Flights have been cancelled due to shortage of pilots. Even though there are enough younger pilots to fill the gaps the problem is that they are not allowed to navigate a plane by themselves. The airline asked that the Belgian government to revise the tax system for pilots in Belgium. A review of the pay scale and conditions are also to be discussed in the next few weeks.
