What's the best way to plan my itinerary to Dublin?

I’ve been planning a trip to Dublin for months, but every time I look at flight prices they seem to shift dramatically. One week the tickets are reasonable, the next they’ve doubled. It’s frustrating because I want to get a good deal, but I also don’t want to spend hours on different booking sites, trying to figure out which route or airline is the most efficient. Plus, Dublin has flights arriving from so many different hubs across Europe and the U.S., so choosing between direct flights or cheaper connections is another layer of confusion. Honestly, I need a more reliable way to compare everything at once.
