In April 2007, the airline company Air Berlin transported 126,452 more passengers on domestic and international flights than in the same month of the previous year. The number of passengers welcomed on board in April 2007 amounted to 1,684,733 (April 2006: 1,558,281), an increase of 8.1 per cent. For the first four months of 2007, the accumulated number of passengers flying Air Berlin rose by 10.6 per cent, from 5,288,759 to 5,850,420.

For April 2007, the fleet capacity utilization rate decreased by 2.9 percentage points to 74.9 per cent (April 2006: 77.8 per cent). The company believes that the unusual weather conditions were responsible for this development: While airlines usually witness a lot of short-term bookings for Southbound flights in April, sunny weather in Germany and persistent rainfall in the Mediterranean region convinced many holiday makers to stay in Germany. Nevertheless, for the first four months of the year, the accumulated capacity utilization rate still showed an increase of 0.8 percentage points to 70.9 per cent.

In April 2007, the following German airports recorded exceptional growth: Berlin-Tegel (+18 per cent) and Munich (+11 per cent). Outside of Germany, Helsinki airport once again took the lead with an increase of 82 per cent, followed by Moscow (+61 per cent) and Zurich (+23 per cent).
