Marketing department at the airport which i believe is now based at Manchester to cut costs
Like MAG told their stakeholders when proposing the sale of Humberside; 'It takes up a disproportionate amount of management time relative to it's size'. I believe that will be the same case for a number of the smaller regional airports, BOH included.
That said, the management at BOH will no doubt have input, and IMO its naive to assume that they aren't talking to current and new operators to try and convince them to open more routes.
