I disagree on why Wizz pulled out. They were establishing new routes but at the same time being beaten up by not enough crew/planes at the established bases. They made a logical decision to concentrate on those (Doncaster was not the only airport they pulled from).
On the Peel front, only time will tell. We know the theory, and now sit to see how it plays out. There are break clauses and if it's not a success the exposure is limited, and Peel get to develop the land. If it is a success, great...
