How Aer Lingus does on this route
Better or worse than the route itself?
Everyone flying Heathrow to Dublin hits the same airspace and the same two airports, so the honest question is not whether the route is busy, it is whether this airline handles it better or worse than the others on it.
Aer Lingus flies 65% of this route, so the right-hand column is mostly its own flights being averaged back at it. The comparison that means something here is against the rest of its network.
Against its own network it is 3 points better than usual: Aer Lingus lands on time 73.4% of the time across all 52,206 of its UK flights a year, against 76.4% here.
In money terms: about 8 flights a year on this route land 3 hours or more late, which is about 1 flight in 1,000. Everyone on board one of those is owed £220 each.
