Act Fast: Fly nonstop to Dublin from Los Angeles, San Francisco from $424 round-trip

Calling all Californians: You can book nonstop flights to Dublin at excellent discounts right now.

Aer Lingus, Ireland's flagship airline, is offering round-trip flights from West Coast cities such as Los Angeles and San Francisco for as low as $424.

The travel window is primarily slated for the months of October and November, aka shoulder season. Late autumn is actually an excellent time to visit Ireland. The crowds at bars and attractions will likely be less cramped, and the weather won't be as rainy as in December.

This deal is for Aer Lingus' Saver fares, the airline's basic economy tier. You will get a free carry-on bag, but if you want to check luggage, it will cost between $55 to $75 per suitcase each way.
