I know little about trains but Belfast figures are only based on Belfast-border to Dublin and the rest are not included from south down when really they are the same line. It is well know the line between Dublin and the border makes the biggest profit per passenger and service levels are bad for the population on the route.
Now back to Westjet and DUB, it was WJ twitter who said we will be sending the B767-300 to DUB so either a mistake or something let out of the bag. I was always under the impression the 767s were fully booked up for LGW ops. Would be great to see an unserved route even at 1-2 weekly.
