Overall it looks as if the only Belfast airline which has seen an increase in pax numbers is flybe. Maybe the aftermath of the BA Connect takeover has worked out in the end?
Looking at the baby routes the cardiff route might be better suited to an embraer of bmi regional if the pax numbers still go down. A 737 is a bit rediculous anyway on this route, I mean apart from people with family in Wales and a few Rugby nuts, who really wants to go to cardiff?
