It seems that the "JOIN" Press Release may be delayed a little longer - possibly even until after Christmas. There are a lot of details such as slot allocations to be finalised first and they don't want the
PR to raise as many questions as it answers. I think once the announcement is made it will be clear to most why the operation has taken time to get up and running.
It looks like Cityjet may be stopping their LCY-EIN route; I wonder if SEN-EIN might work for them.
