City Airport may have higher fees, but this could be recouped from higher fares from business travellers. City Airport also has a surprisingly strong leisure market.but i believe city airport may have higher fees than say southend. and yes both being stobart airports will make things easier and possibly cheaper.
and by that logic everyone should fly to city airport as its more attractive. attractive to people who actually need that side of town of course but not to those who may want the west side of town which would be heathrow otlr the southern end of town for which gatwick is more attractive or even the north and north east which would make luton and stanstead more attractive and so on and ao forth
And where did I say "everyone" should fly to City Airport? All I said was that flights to City would be more attractive than flights to Southend. It was a generalisation.
