2015 is turning out to be the very good year, passenger figure-wise, that was anticipated in the early spring with the Flybe announcement and is likely to see around 1.15 million passengers. This would be the best year since 2011 when the airport handled 1.208 million.
2016 ought to exceed 1.2 million. CWL's best ever year was 2007 when 2.094 million passengers used the airport. To get back to that level would almost certainly require a major low cost airline coming in with a substantial presence.
