What most people said
- Nearly everyone says allow 3 hours for US flights, as you clear US preclearance in Dublin; add time if returning a hire car.
- Some got through much faster, but most say it isn't worth the risk.
- Eat before US preclearance: there are many more food options before it than after.
- On arrival, most allow 1 to 3 hours and give the car hire firm your flight number so they know about delays.
What people said
- Minimum of 3 hours - add an extra hour if returning a rental. Better to eat before preclearance as offerings after are limited. Also be aware that bringing food through preclearance is restricted.
- I usually just put the flight arrival time as the pick up time and the flight number so they can then see if it's delayed.
- Kerry flight arrives in Terminal 1, US flights go through Terminal 2 (some Canadian through T1).
