To be basic: everything is the same....
High turnover of staff, crew etc. since people has a tendency to work for whoever offers the best Ts & Cs, meaning low seniority and experience.
SAS has decided that Cityjet is a strategic (long term) partner, in other words: Cityjet cancellations har no consequence, as long as it can be argued why (tech. problems, lack of staff etc). SAS will just rebook passengers to other flights.
There will be no adjustments in how management decide to run this company; hence they have decided to copy Ryanair, but in an other segment (ACMI).
