I am looking at flights from Paris to Dublin on May 22nd. Is this a good time to buy, or should I wait? For example, I am looking at an Aer Lingus flight that leaves in the early afternoon for around $125. I am not interested in early or late flights.
Buy it now if you do not like to see the price go up. I see it for 84 dollars one way

The higher amount I mentioned was for the Smart Fare which includes checked baggage and advance seat selection.
go ahead and buy it
Unlike trans-Atlantic flights, flights within Europe only go up in price the closer you get to travel. Once upon a time, when Ryanair and Easyjet were new, they sometimes had last minute sales to fill planes. They aren't new anymore, and haven't had difficulty filling their planes for a long time, so those last minute discounts are a thing of the past. In fact, the opposite is true - if you wait, prices can go up sharply as the planes fill.
