Skyguide is to raise the unit rate for its route charges by 4.9% with effect from 1 January 2011. The increase has been prompted by a decline in en-route air traffic volumes, which is itself a product of the recent economic crisis. The approach charges will remain unchanged. Despite suffering sizeable revenue declines, Switzerland’s air navigation service provider has kept its charges stable over the past few years. But skyguide will only be partially able to offset the revenue shortfall expected for 2011 through further cost economies.
