I believe that Jet2 is a 3 aircraft base at BFS this summer. Could be wrong. In the NI Travel News press release it stated that there will be a 7 per cent increase in seats for summer 2019 over summer 2018, and lists routes that will utilise the larger -800 aircraft. So I believe this is where the additional seats will come from. However then goes on to state that 4 aircraft will be based at BFS for summer 19.
With the use of larger aircraft and if an additional aircraft was based, would the increase not be assumed to be larger than 7 per cent?
On the back of a bumper Summer 2018 programme, there is even more growth in response to demand for Summer 2019. The addition of 30,000 seats means over 450,000 seats are going on sale, a 7 per cent capacity increase, which will be supported by four aircraft at the base.
