DeborahFlew with Aer Lingus-Jun 2025
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.
Verified travelerFlew with Aer Lingus-Jun 2025
If you’re doing a transfer speak to someone at the desk don’t use an automated kiosk
KillianFlew with British Airways-May 2025
Dublin airport a shambles when it comes to collecting luggage or getting a cab. Allow plenty of extra time.
ThomasFlew with Aer Lingus-Oct 2024
You will likely have to walk a lot more than you might expect to make a connection.
