I think it is just a case of airports getting p1ssed off with receiving little or no airport taxes from Ryanair, yet Ryanair quite happily collects (and bags) the full amount of taxes from the pax.
I hope other airports will follow Newquay's lead. If this model is rolled out universally, pax could be asked to pay all the airport taxes directly to the airport, preventing Ryanair and other locos from embezzling these taxes ! Then lets see if FR are still able to market seats for 1p (plus taxes - payable to the airport)
