Follow The Points Guy on Facebook and Twitter, and subscribe to text message alerts from our deals feed, @tpg_alerts.Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency, such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using the American Express Platinum Card, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.A few days ago we posted a deal for two people from New York to Athens for just $975 total. But if you’d like to visit the capital of Greece and don’t have a travel companion, now you can get there for just a few dollars more. OneWorld partners American, British Airways and Iberia are currently offering flights to Athens (ATH) from New York (NYC) and Philadelphia (PHL) starting at just $538 round-trip.Flights are available departing on many Tuesdays and Wednesdays between late August 2017 and February 2018 except for the December holiday season. You don’t need any tricks to get these prices, so just use Google Flights to find the dates you want, then book on Orbitz, Expedia or directly with the airline itself.Most of these itineraries have one reasonable connection, but if you’re willing to make an airport change in London between Heathrow and Gatwick or do an overnight in Madrid (MAD), you can actually get the price down a few more dollars to as low as $525. Also, since these are international trips on a full service carrier, you’ll get your first checked bag free and even a complimentary meal during the flight.Airline: One World partners (Iberia, British Airways, American)Routes: NYC/PHL to ATHCost: $538+ round-trip in economyDates: Late August 2017-February 2018 (except the holidays)Booking Link: Orbitz or ExpediaPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare) or Chase Sapphire Preferred (2x on travel)Here are a few examples of what you can book:Philadelphia (PHL) to Athens (ATH) nonstop in October for $538 round-trip via Orbitz:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
