Don't discount the possibility of Jet2 revisiting the idea of a base in Mainland Spain or the Canaries. This would provide for resilience, and offer the option of operating sectors to unserved UK airports such as LGW, ABZ, NWI, LPL, BOH, CWL etc where a full base may not be practical for reasons of either slot availability or market size. If their services are to UK airports exclusively, operation of G-registered aircraft should not be an issue, unless I am misunderstanding the regulations?
