There does seem to be a problem with the CAA stats for BOH at the moment. Up until recently, when I totalled the individual routes this total was usually within a hundred pax or so of the CAA Terminal & Transit Pax total (for June and September 2018 it was spot on!). However, for the past 4 months they have been way short so either there are a some routes missing, which seems unlikely, or some of the figures are too low, possibly those for the Canaries?
November 2018 2261 short
December 2018 4431 short
January 2019 2954 short
February 2019 1611 short
