Deal of the day: Fly business class to Dublin for just 45K miles during peak season

15 hours ago 1

We are already well into the summer travel season, and while there is still time to plan a last-minute getaway, you should also start thinking about where you might want to go this fall. This is especially true if you want to travel abroad, because you should book your flights three to five months in advance for the best deals.

Speaking of international travel deals, we found a great price on business-class flights to Dublin on Aer Lingus and American Airlines this summer and fall — both bookable via Alaska Airlines Mileage Plan — from just 45,000 miles each way.

Summer is peak season in Dublin. Crowds and airfare are typically higher, making this a great deal. If you visit in September or October, temperatures are milder (pack a sweater!), the crowds are a bit better than in the summertime, and you'll get to enjoy the fiery orange fall foliage.

Here's how you can book a business-class award flight to Dublin for as little as 45,000 miles.

Note that prices and availability were accurate at the time of writing.

Is this a good deal? Cash fares for this one-way business-class seat to Dublin cost about $5,000, which means that by redeeming your Alaska miles, you'll get about 11 cents per mile. TPG values Alaska Mileage Plan miles at 1.5 cents per apiece, per our July 2025 valuations. Therefore, this is an incredible value to help you maximize your rewards.

How to find and book TPG's deal of the day

We used the time-saving Seats.aero tool to quickly find award availability between the U.S. and Dublin. This tool makes it easy to see which dates are available to or from your desired airport.

We've seen good availability through mid-October, but you'll need a Seats.aero Pro account to search beyond 60 days in advance.

When compared to the cash rates, which can climb higher than $5,000 each way, redeeming as few as 45,000 miles for a business-class flight to Dublin is a great value. And, you'll arrive well-rested and refreshed thanks to lie-flat seats and luxury inflight dining.

If you do not have Alaska miles or Bilt Points (which transfer to Alaska's Mileage Plan at a 1:1 rate), you can also book an award flight to Dublin for 50,000 Avios through British Airways Club. While you will spend about $146 in taxes and fees for this redemption, British Airways Club is a transfer partner of most major credit card issuer programs, including American Express Membership Rewards, Chase Ultimate Rewards, Capital One miles, Wells Fargo Rewards and Bilt Rewards. Therefore, it could be worth the additional 5,000 points and $120 in taxes and fees for a lie-flat business-class international seat.

Even with the additional cost, transferring and redeeming your points through the British Airways Club will still get you a value of 9.76 cents apiece.

Though British Airways Club is not a direct transfer partner of Citi ThankYou Rewards, since you can transfer Avios between loyalty program accounts, you can transfer your ThankYou Rewards points to Qatar Airways Privilege Club (an airline program that also uses Avios) and then transfer your Avios to your British Airways account.

How to earn the points or miles required for TPG's deal of the day

Here are some great cards that earn Alaska Airlines Mileage Plan miles or offer the ability to transfer points to Alaska Airlines Mileage Plan or British Airways Club:

Bottom line

With cash rates for business-class flights regularly higher than $5,000, this is a great deal for flying to Dublin in peak season.
