The problem is with the CAA's April 2017 figures. The monthly total for April 2017 was 63,469 but around 47,000 of these are missing from the monthly (and hence annual) route analysis figures. Only Paphos, Arrecife and Geneva appear to be correctly accounted for. Palma, Las Palmas and Tenerife appear to have charter figures but not scheduled and the rest have no figures at all.
