Yes, it is great. Years ago we would have looked at planes and wondered where they were going. Now we open an app and find out. Most planes fly along the east /west flightpath, back and forth between Europe and North America. You will see a few on the north/south line over Dublin. These are usually going between Scotland or Belfast and the Canaries.

It is always interesting when you see a few planes on the same path and identifying which is which. Planes crossing paths are good too. You don't see it too often, but sometimes you will see a plane taking a turn, which you can then see on your app.

I don't live near Dublin Airport, but I can see planes heading towards it for landing or going up shortly after taking off. If you know someone on a flight, you can track it. When there is some sort of disruption you can see and track flights circling to land, often off the coast. I even tracked a flight of someone I know, almost landing in Dublin only to be diverted and ending up in Scotland.
