The 45,000-mile round-trip price this post once covered has ended. What's still useful is how to search Boston (BOS) to Dublin (DUB) with points and miles today, and which programs actually fly the route.
Aer Lingus, Delta and JetBlue are reported to fly Boston to Dublin nonstop. Schedules change by season, so confirm the flights for your dates on each airline's site before you plan around one.
Search Aer Lingus With Avios
Aer Lingus runs its own AerClub program, and Aer Lingus Reward Flights are priced in Avios on a published chart by zone, with separate off-peak and peak levels. The chart prices one-way flights, so a return costs twice the figure shown. Aer Lingus lists December 18 to 31 as peak for the rest of 2026.
Log in to AerClub on aerlingus.com, search Boston to Dublin and check the dates you want. Because pricing is per direction, search each way and compare.
Search Delta With SkyMiles
Delta prices award tickets dynamically and publishes no award chart, so the SkyMiles price for your date is whatever delta.com shows when you search. Don't plan around a number you read somewhere else.
Fund the Booking With Transferable Points
Amex lists both Aer Lingus AerClub and Delta SkyMiles as Membership Rewards transfer partners at 1:1, with an estimated transfer time of 48 hours. Our Amex transfer partner guide has the full list.
See the seats on the airline's site before you transfer, then check the taxes and fees on the booking page before you confirm.
Your Next Step
Start with an AerClub search for your dates, then run the same dates on Delta. If one shows a price you like, transfer only what that booking needs.
