Heathrow bosses want the CAA to allow them to increase airline charges at the west London airport from the equivalent of £19.33 per passenger for 2012/13 to as much as £27.30 for 2018/19.
Gatwick chiefs want to be free of CAA regulation altogether and have argued for a new seven-year, regulation-free regime which would equate to the per-passenger fee going up from £8.80 in 2014 to a maximum of £10.68 in 2020/21.
At Stansted, Ryanair chief executive Michael O'Leary has long railed against what he sees as excessive airline charges and has been particularly scathing of the CAA as a regulatory body. CAA's announcement represents it's initial proposals with a final decision due in January.
