Flights from Dublin to San Francisco: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Dublin to San Francisco 
Verified travelerFlew with Aer Lingus-Aug 2026
Get to Dublin airprort early due to extra inspection and security clearance for US bound flights
MichelleFlew with Aer Lingus-May 2025
Make sure you arrive well ahead of the flight. We were lucky that security lines were pretty short but they could be very long and you do US customs and security in Dublin.
NinaFlew with Aer Lingus-Nov 2024
Make sure you include extra time to pass through US Border Control if you’re flying to the US! Also Aer Lingus bag drop closes 75 mins before flight departure for long haul so bear that in mind!
