Frequently Asked Questions

When is the cheapest time to fly to Portugal?

January through March offers the lowest fares, with TAP sales bringing roundtrips from NYC/Boston under $400. The Azores often have even cheaper fares — sometimes under $300 roundtrip.

Should I fly into Lisbon or Porto?

Lisbon has more US routes and is the TAP hub, so fares are typically cheaper. Porto is ideal for northern Portugal and the Douro Valley. Consider flying into one and out of the other.

What are the Azores?

The Azores are nine Portuguese islands in the mid-Atlantic, roughly 4 hours from the US East Coast. They offer dramatic volcanic landscapes, whale watching, and hot springs at a fraction of mainland European prices.
