News site Quartz, recently teamed up with flight search engine Hopper, to present a tool that helps you find cheap flights from some major US airports to select destinations (US and international), with Athens being one of them.
The results aren't really that surprising - if you want a cheap summer flights to Athens you're out of luck - but the tool does help you to come up with some ideas and focus your search a bit if you're not really set on certain dates.
For five US airports (Baltimore, Boston, LA, Miami and NY LaGuardia) the cheapest Athens flights can be found in the fall. For another ten (Atlanta, Chicago O'Hare, Dallas, Houston Bush, NY JFK, Newark, San Francisco, Seattle, Washington Reagan, Washington Dulles) the cheapest flights are during the winter. So, if you're a New Yorker start your search by LaGuardia in the fall and JFK or Newark in the winter, not that the one is necessarily cheaper than the other (different airlines use different hubs). So, maybe this is just a publicity trick and I took the bait! But it's a good reason to start you thinking about a non-summer vacation to Greece, especially if you're less tolerant to heat and you live in a place that enjoys a reasonable amount of sunshine in itself.
