Further rapid growth in passenger numbers and flight movements is expected for 2012. This represents a risk for the stability of flight handling, especially as an adequate infrastructure, such as the terminal extension at Frankfurt Airport, is not yet available. Lufthansa has taken measures to simplify and expedite ground processes, such as increasing process automation by means of check-in machines and self-boarding for instance. Here again, external influences cannot be ruled out, however. The recruitment bottleneck at German air traffic control is expected to persist in 2012 for example.
