Flights to Spain are cheap right now, with fares starting at $357 round-trip.

The Airfare Spot first noticed the cheap flights to Spain yesterday, when the Houston to Madrid route dropped to $473 round-trip and tickets to Barcelona from Atlanta, Denver, San Francisco, Salt Lake City, and Washington, D.C. dropped as low as $414.

Thrifty Traveler announced that a number of airlines had entered into an all-out airfare war, and expanded the sale to include popular Spanish holiday destinations like Alicante, Bilbao, Ibiza, Mallorca, and Seville.

Later, Scott’s Cheap Flights found additional deals to Valencia, Santiago de Compostela, Tenerife, and Santa Cruz Palma.

At this time, the cheapest possible ticket seems to be on sale from New York City to Barcelona — a cool $357 round-trip with United in June.

Cheap flights are available with a number of competing airlines, including American Airlines, Iberia, British Airways, United Airlines, and Norwegian Air.

While availability and ticket prices can vary depending on your route, the most inexpensive fares are typically found on flights to either Madrid or Barcelona, between January and May, and between September and November.

To book this deal, use Google Flights’ low-fare calendar to select the most inexpensive travel dates from your home airport. Then, search for those dates in a search engine like Skyscanner or Momondo to get the best possible deal.
