From a high point in the period 2005 to 2008 when annual passenger numbers ranged between 246,000 and 253,000 there has been a gradual decline although the years since 2010 have been relatively static with annual numbers between 165,000 and 176,000.
EZY have run the route throughout this period, so must have a good understanding of the numbers. Clearly they can make more money elsewhere.
