View the current offers here.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 Platinum Card® from American Express, 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.As mainstream airlines continue to compete against low-cost carriers on routes to Europe, customers are the winners as prices fall. Today we’re seeing another example of this as American and oneworld alliance partner Iberia are offering great deals on summer airfare from the US to Madrid, Spain (MAD) — from just $395 round-trip.You can fly from both New York (JFK) and Los Angeles (LAX), and you don’t need any tricks to get these deals. Most of these fares are available from August through October of 2018. Search for the dates you want with Google Flights, then book on Orbitz, Expedia or directly with the airline itself. Also, since these are international trips on mainstream carriers — and not in Basic Economy — in most cases passengers will get their first checked bag free and a complimentary meal during the flight.Airlines: American, IberiaRoutes: JFK/LAX to MADCost: $395+ round-trip in economyDates: August through October 2018Booking Link: Orbitz, Expedia or with the airline itselfPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (5x on airfare) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:New York (JFK) to Madrid (MAD) for $395 round-trip on American and Iberia via Finnair:Los Angeles (LAX) to Madrid (MAD) for $395 round-trip on Iberia via AA:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
