Sorry - but what makes you think that a little commercial benefit justifies an increase in CAS? Nasty little loco charters have chosen second rate airports to fly from purely to cut costs in order to offer yet cheaper flights to alcohol-fuelled oblivion for the pierced, tattoo'd, shell-suited dregs of society. That is no justification for demanding increases in CAS - these 'airlines' (I use the term loosely) chose these cheaper aerodromes in the full knowledge that the airspace between the ATZ and the airways was only Class G...
Currently, ThomsonFly are pushing for an airspace-grab at Coventry. There is no intrinsic need for this - it would merely benefit their shareholders. They should thus accept that there are only 2 options for them:
1. Accept the status quo and the associated cost.
2. Sod off somewhere else where there is the category of airspace they think they need.
There is absolutely no justification for any increase in CAS in the UK - there's plenty as it is. Tough doo-doo if it means that costs of flights to Argos, Asbestos, Domestos and the like will cost €10 more - I have absolutely no sympathy.
