Cityjet have said that they carried 23000 passengers on Dublin London City in May, this represents as we know a huge increase for them over last year when in May 2014 they carried almost 16000.
Hence, BA Cityflyer carried over 14000 passengers, total numbers on the route for May were 37434.
So split is Cityjet: BA; 60:40.
Thought this may be on interest to those interested in the Dublin thread...
