This morning, the Airfare Spot found ridiculously low fares to cities across Spain from Philadelphia, Dallas, or Miami.

For $365 round-trip, travelers based in Philadelphia and Dallas can fly to Madrid or Barcelona from September through mid December. Miami-based flights are available from September through November, and will cost between $395 and $404. For more information on these tickets—all of which are being sold by United—click here.

Delta and KLM, on the other hand, are offering cheap tickets to the Spanish port cities of Alicante, Palma de Mallorca, and Bilbao from the same three U.S. gateways. Flights depart Dallas, Philadelphia, and Miami from September through October or November (depending on your destination).

Trips to these cities start at $470 round-trip, and offer a perfect excuse to either take a rustic, affordable trip to Mallorca or to splurge at one of the best new hotels of the year. After all, why choose when the Sant Francesc Hotel Singular boasts offers travelers tradition and five-star amenities? Think: Santanyí stone pillars, and an on-site restaurant in former stables with an impressive list of local wines.

Recently, Norwegian hosted a similar sale to Malaga ($415 round-trip) from New York City, Boston, Los Angeles, and San Francisco. If the trend continues, tickets from the United States to Spain could regularly be found for less than $500.
