Portugal 
in $550s-$600s RT

We don't want to jinx it, but it seems like some those fuel spike Euro prices might fiiiiiiinally be coming back down to Earth. It's been a hot minute since we last saw anything under $600 RT from the West Coast! Hopefully this is a good omen and not just a blip on the radar.
When it comes to Portuguese flights, it's kind of a tale of two cities: Lisbon and Porto. You really can't go wrong with either, but Lisbon's more of an energetic, jam-packed city, and Porto is more traditional and cozy. Lisbon comes with a side of castles; Porto comes with a pairing of Port.
And since they're only three hours apart by train, you can hit both either way :-)
