UPDATE: This fare offer is dead.
There have been some good deals popping up today for travel to Europe but this has to be the best one so far! Not sure how long it will last so get moving on it if it sounds of interest to you!
Great Deal: NYC – Dublin From $335 Roundtrip!
Finding the Fare
To find the best range of dates with the price, start your search at Google Flights. They will allow you to use flexible dates in searching and show you the options available to you before giving you the places to book the tickets.
It works for leaving from NYC airports (JFK/EWR/LGA) and heading to DUB (Dublin, Ireland) and returning to one of the NYC airports. The roundtrip price is an awesome $335! The one below is $340 but I was also able to get a $335 one at AA.com
It is available with US Airways/American Airline flights (including the non-stop out of NY). The fare is bookable on Priceline and possibly other OTAs. With Priceline, you have until tomorrow to cancel the ticket if you decide not to go through with it. If you purchase on AA.com, you cannot cancel the ticket after purchase.
I have found dates from September through February of 2016 so check it out and have fun! I will update this post with other possible cities but I wanted to get it out quickly so you have time to book!
Edit: According to this post from The Flight Deal, there are several other options available throughout Europe as well. They are not this cheap but can be had for around $500 and from locations all over the US! Head on over to The Flight Deal to check them out!
