I highly doubt a deal has been made in the matter of a few weeks between an airport and an airline.
Their post on their site also goes on to mention Lufthansa and other named airlines, I highly doubt there are deals and more name dropping than anything. It's a talking shop and nothing more. The point that's being missed it, Viable have to prove it can be viable as an airport and they're doing the complete opposite right now, practically confirming its non-viability (I think it is Viable - just not with these daft proposals). Look at Aberdeen, small rway extension and improved technology cost £10m. These plans for PLH will easily run in to £25m+ - it's not going to happen.
