Airports operator BAA said on Thursday the UK Civil Aviation Authority should ease regulation of BAA's trio of London airports.

"BAA is asking the CAA to consider removing those activities from the regulatory domain that are already subject to significant competition, namely advertising, long-term car parking and bureaux de change," the airports operator said in a statement to the London Stock Exchange.

BAA was responding to the CAA's review of caps it sets every five years on the fees that BAA charges airlines to use its London airports. The latest caps will apply from April, 2008.

BAA owns the three main London airports, Heathrow, Gatwick and Stansted.

The CAA said in December it planned to regulate each of the airports on a stand-alone basis, ruling out the cross-subsidisation of projects such as a second runway at Stansted from charges at other airports.
