As has been said so often the BRS growth is mainly in the hands of existing airline partners. The airport seems convinced it will breach 10 mppa by 2021. Assuming that 2018 finishes somewhere around 8.6 mppa, possibly edging up towards 8.7, that would leave 1.3/1.4 million extra to be found in the three subsequent years - average 400/450K per year. After the tremendous surge in the three years 2015, 2016 and 2017 when passenger numbers increased by over 1.9 million passengers - a growth rate of 30% in three years - anything markedly less than that rate of growth might be seen as less interesting by airport followers. 2015 saw an additional 448,000 passengers 2016 an additional 823,000 2017 an additional 630,000 The early years of this century saw similar passenger growth numbers and because the base numbers were much lower than they are now the percentage gains were far higher. 2018 is likely to see around another 400,000 passengers, and to reach 10 mppa by 2021 a similar sort of average passenger numbers growth would be required over the three years after 2018. I emphasise that I'm writing this from the viewpoint of maintaining interest in a BRS-related aviation message board which is far removed from the practicalities of a well-run and profitable airport that BRS undoubtedly is. It would be good to have one or two more airlines but if that then skewed the balance of the airport's network as a whole with a resultant reduction in routes/frequencies then I would certainly not be in favour. Thank you for the views and suggestions expressed since my post yesterday. They are very much appreciated and valued.
