The flights might be full but I've heard the yields are low, so while it's a good feeder into the network it doesn't make much money because it's filled with holidaymakers and emigrants, not business people.

I'm amazed they are still using a 3-class plane at all. More often that not first class is empty, business 50% booked and economy overbooked (so it's a good route for upgrades). They often substitute a 2 class plane (adding 68 extra seats). The next 5 days appear to be 2 class.

So the A380 is the wrong plane for Dublin. Maybe a 2-class version might work, but the airport itself isn't ready for A380 anyway.
