For your trip from Los Angeles to Dublin, it's best to book your flight around 100 days prior to departure when prices are at their lowest around $784. You can also find similar prices from 144 to 65 days before departure. Avoid waiting until the last 55 days as prices begin to rise significantly, reaching up to $1,029 close to departure—nearly 29% more expensive. Booking early reduces your risk of paying higher rates as departure approaches.
