Fly from Dallas to Milan, Italy for $530 round-trip, including all taxes, on Lufthansa.
With two connections, this isn't the breeziest of itineraries. But it is cheap! And if you'd like to go to Italy, it's worth the effort. We found only a few dates available in March. See our Fare Details for booking info.
We also spotted a reasonable fare from Dallas to Florence, and Bologna, and -if you prefer France- we even found a great deal to Lyon and Nice. We're still checking what else is out there, but in the meantime visit our Dallas listings.
