The UK's Competition Commission says airport charges at Stansted Airport should be put up by about 3.5% in 2009 or 2010.
Despite the impact of the economic downturn on the industry, the Commission has ruled in favour of charge increases at the airport, which serves London, during each of the next five years.
Airlines are expected to pay Stansted operator BAA, which is owned by Spain's Ferrovial, £6.34 per passenger in 2008/09.
The commission said this should now rise to £6.56 in 2009/10, and to a maximum of £7.05 by 2014.
BAA had asked for a higher sum, but the recommendations are still likely to increase calls by Ryanair for airports regulator the Civil Aviation Authority (CAA) to be overhauled and for BAA to be forced to sell Stansted.
The commission repeated earlier findings that the running of Stansted as part of a London monopoly by BAA was against the public interest.
It said the operator was guilty of running ineffective security queuing and not consulting properly over airport expansion.
The CC earlier this year said BAA should have to sell two of its three London airports and one in Scotland. BAA promptly put London's Gatwick up for sale.
