Jet2 are Bridgepoint's biggest customer at LBA, and LBA is Jet2's largest operating base, its HQ and arguably the base where it has the most favourable combination of catchment size & competition. One would have thought it not at all unrealistic to expect the two parties to come to some sort of arrangement e.g in return for a committment from Jet2 for growth and route development, Bridgepoint would commit to favourable commercial terms and directing some of their £70m 'pot' to improving the airport's low-viz defences.
Rising interest rates, increases in APD, the green lobby, lengthy airport security queues etc are all reasons for people simply not to bother and spend their money on something else. In light of this I would have thought any "beancounter" would be commecially astute enough to recongise that investment in the reliability and smooth operation of the services offered by airports and airlines is money well spent in the long term.
