Miraculously, last week's big nationwide fare war to Europe has managed to stick around through the weekend, and we're finding even more routes on sale today.

Rules and restrictions may vary slightly by route, though you'll find the majority of these deals are valid from October through March 2017.

This little battle between among major carriers is not an advertised sale, meaning these fares could vanish at any moment. If something catches your eye, better move fast.
