I just got back from Dublin and thoroughly enjoyed it! Crisp weather, nice parks, great museums, and a few beers - I can’t complain. I’m already planning my return to Ireland to see the countryside. Luckily, getting to Ireland isn’t too difficult with Aer Lingus and the US Big 3 servicing multiple US cities.

Anyways, here are some dates you can fly Aer Lingus business class for as low as 45k points each way with Alaska Miles.

3) Calendar view should pop up. But you will want to add some filters to better see which dates have “saver” business class seats. Choose “Nonstop only” and “Business/First” class. Then you should be able to see which dates have award availability. Confirm availability with your preferred booking partner, transfer points, then book!

To book with Aer Lingus

1) You will need to log in to your account or create one if you haven’t already.

2) You can click here to visit the Aer Lingus Avios reward site, or you can get there from the Aer Lingus site. On the homepage, hover over “AerClub” and choose “Book a Reward Flight”. Then you will have to click an option that says “Buy a Reward Flight” that will redirect you to another Aer Lingus site that lets you use Avios.

3) Put in dates and destination, and I personally like to search for one-way flights. Then hit search.

4) Find the dates that work for you and book. Don’t forget, Aer Lingus uses Avios which can be freely transferred across other Avios programs such as British Airways, Qatar Airways, Iberia, or Finnair. Although all these programs use Avios, they all charge a different amount with Aer Lingus having the best pricing.

Aer Lingus business class experience

Flights will either be on an A321 (narrowbody) or an A330 (widebody). Some seats are certainly better than others (throne seat!) unless you want to sit next to P2.
