Best Booking Windows
For the best fares on San Francisco to Dublin flights, consider booking during shoulder seasons (April–May and September–October) when demand is lower but weather remains pleasant. Midweek departures (Tuesday and Wednesday) tend to offer lower fares than weekend flights. Booking 6 to 12 weeks in advance for peak season and 4 to 8 weeks for off-peak periods typically yields better prices.
Baggage and Fare Notes
Transatlantic baggage rules differ from European short-haul flights. Before booking, review the Aer Lingus baggage allowance for 2026 to understand what is included with your fare type. Adding bags at booking time is typically cheaper than adding them later or at the airport.
