Despite the report setting out recommendations for short term measures to boost UK aviation capacity, over 100 days have passed without an official response from the government. The Airports Commission was set up in 2012 by the government to examine the UK's airport capacity needs and options to meet those needs. The December 2013 interim report stated that there is a need for one additional runway that must be in operation by 2030 for the UK to meet its economy's aviation demand. Heathrow Airport is cited by Let Britain Fly as a leading candidate for the new runway. The interim report is to be followed by a final Commission report to be published after May 2015. The Let Britain Fly director, Gavin Hayes, says: "Over 100 days ago, the government's Airports Commission set out clear recommendations on short-term steps that would relieve pressure on the capital's over-capacity airports."In Hayes view, not only has the government failed to take these steps, it has not even responded to the recommendations. "There is no justification for this lack of action," he adds. Hayes' campaign sees the government's failure to make a decision on airport expansion as "strangling UK growth". Once introduced, the Airports Commission's short-term recommendations would contribute £56 million to the economy in 100 days, according to Let Britain Fly.In reaction to the December 2013 publication of the Airport's Commission's interim report, Let Britain Fly called on the leaders of the UK's Conservative, Labour and Liberal Democrat parties to publicly support the view that more runways are now needed in London and the South East of England. The campaign also called on the politicians to commit to taking immediate action following the Commission's final report in 2015.
