DC to Madrid

I was able to find round-trip flights from IAD to MAD in September 2025 for $398.91. That’s an incredible deal, though keep in mind that you’ll need to pay extra for seat selection and baggage.

You can also add a free stopover on TAP Air Portugal, allowing you to spend up to 10 days in another city.
