Air fares will “increase significantly” if UK airports become too congested, aviation regulators have told the Government.
Capacity constraints at many airports will “increasingly limit the choice and value available to consumers”, said the Civil Aviation Authority (CAA).
It added that this was particularly true of the South-East, where the Government has ruled out expanding Heathrow.
In a report entitled Aviation Policy for Consumers, the CAA said the Government needed to put air passengers at the heart of its thinking.
“Fares at congested airports are predicted to increase significantly as a result of capacity constraints,” the CAA report said.
