The problem with the month on month stats is that the numbers of pax/flights are often so low that events like weather can have a big impact e.g. the 9% increase at MME is about 600 pax, couple of more days of dodgy weather in 2015 than 2016?
Interesting also to compare the two KL/AF partner airlines at NCL - KL seem to be able to flex easily, i.e. they have operated a number of 739's this week but also a number of EMB's on 737 flts, whereas the AF only seems to change from the 146 due to tech issues.
Are CDG loads less volatile, AF less flexible or does the arrangement with CityJet get in the way?
