Heathrow seems to have a lot of plane traffic so make sure you have a good cushion of time if you have connecting flights. I had a 2 hour layover but ended up having to run to make sure I got to the other gate in time.

If you’re doing a transfer speak to someone at the desk don’t use an automated kiosk

Dublin airport a shambles when it comes to collecting luggage or getting a cab. Allow plenty of extra time.
