TAP Air Portugal has put nearly all routes from North America to Europe on sale in the $300s range. The best part is that these fares are widely available throughout the year, can be booked one-way for around half the roundtrip price, and offer the chance for a free stopover in Portugal. Roundtrip fares are as low as $271.

Although many of these routes may require a long or overnight layover in Portugal, you can theoretically take advantage of this and extend your stopover up to 5 nights and really enjoy a second city on your journey for the same price as one roundtrip flight.

I say "theoretically", because I found it quite hard to find the same price if I added a multi-day stopover to these roundtrip fares. However, if the route requires an overnight stay, you'll easily be able to have one night in Portugal either to or from your destination.

You may find better deals on nonstop flights or better connections with other airlines on scattered travel dates, but these TAP Air Portugal fares have excellent availability for daily travel from March through June, and again from August or September onward. And there isn't any minimum stay requirement that most other carriers have on the lowest fares.

This sale is unadvertised and prices may jump at any time. Book quickly to take advantage of these incredible deals.

These are TAP Air Portugal's "discount" fares, which only include a carry-on bag plus one personal item. Other restrictions apply. Consider purchasing the "basic" fare if you need checked baggage allowance.

It's always cheaper to purchase the basic fare, which includes one checked bag (usually $35 more each way) than to pay for a checked bag on the discount fare. Compare this upgrade to what it costs to check a bag on other carriers (usually $60 each way) and these TAP Portugal fares are a real steal if you travel with checked baggage.

Need a one-way ticket to Europe? Many of these fares can be booked one-way for around half the roundtrip price.
