When is the best time to travel to Ireland with cheapest flight ticket?
There aren’t any nonstop flights between SFO area airports (including OAK, SJC, and SMF) and Spain–so you couldn’t get a stopover due to connecting there–but Aer Lingus does fly nonstops between SFO and DUB. Earlier is better, as most airlines begin peak season pricing for transatlantic trips on June 1. Using ITAsoftware.com, I see SFO-DUB with a connection at Heathrow each way for $769 currently. This departs May 13 with 1 month stay. The nonstop Aer Lingus flight is about $140 more currently. I would not expect fares any cheaper than this by waiting too long. In fact, for a May departure, transatlantic, I would want to book no later than 2 months advance. I would also want to sign up for sale fare alerts here: http://www.farecompare.com/search/year-h… If you’re not staying a month (I just guessed) then
