We all know that the air traffic will have some troubles due to many reasons, oil prices in the first place.
But the traditional airlines, like Air France or British Airways, will always have their daily, and high profitable, customers : business man ahead.
Low-cost will have to face to increasing exploitation costs, which obviously means that ticket prices are going to rise, and the numbers of passengers will, on the contrary, decrease due to the type of customers.
On my mind, low-cost airlines are really in a bad configuration right now.
