asyjet.
It’s basic supply and demand. Multiple airlines fighting over a few low paying pax means tickets will be cheap. With only EasyJet the prices will rise as the cheap tickets sell first. This perfect set up you envisage isn’t going to happen. Everyone has pointed out the flaws but you just call us EasyJet fans.
If this demand is there, get in touch with airlines. As mentioned, someone like Sun Air but they are not going to do it for £150 return. They operate Billund-LCY (or did until COVID) at around £350 each way. You need a VLM type carrier who operated reasonable prices and business schedules but they are gone. Eastern are not interested (and are usually more expensive) and Loganair have said they want a subsidy. It’s just not an attractive market and the numbers are too small for anyone to want to create a base there without some financial support.
