WW seemed to indicate a search for a franchise partner does not have to be limited.
CityJet regarded as a competitor with/for the franchise so perhaps they/Falko are looking to "eliminate" the incumbent eventually in the negotiations for a nominal sum along with Falko assuming debt which in their business affairs they are not averse to.
Perhaps break clauses in the Franchise can ultimately be effected before 2022 but IAG/EIN hold all the cards.
Anyways it appears the revolving doors will be working overtime in Dublin.
