[12/15/2017 @ 3:01 PM CT] Fare gone. Removing from deal list.
AA and Oneworld partners have round-trip flights from Chicago (ORD) to Brussels, Frankfurt, Zurich, or Vienna (BRU/FRA/ZRH/VIE) for $464-$506 with a connection. Flights from February to April. 6-day minimum stay required. Flight may operate as a British Airways/Iberia code-share.
Note: Icelandair has Frankfurt for $434, but the fare doesn’t include bags and it will actually cost more than booking a “Regular Economy” fare on a competitor once you pay all the fees for stuff you actually need.
