Britain's competition watchdog has slammed London's Heathrow and Gatwick airports for their level of service to passengers, particularly their failing to manage queues, and called for service regulations to be tightened.
Britain's Civil Aviation Authority (CAA) said that, in response to criticisms made by the Competition Commission, it would now work on proposals to improve service.
'The Commission has found that Heathrow and Gatwick airports, in failing to manage security queuing and queue times to avoid unacceptable delays to passengers, crew and flights, have acted against the public interest,' the CAA said in a statement.
Heathrow and Gatwick airports are run by BAA, a division of Spanish construction group Ferrovial.
