Right now is a great time to visit Europe.Flights to some of the continent’s most desirable destinations are on sale, with some of the best prices available for travel to Portugal. Spain’s culture-rich neighbor is one of those countries everyone should visit at least once. Now you can visit places like Lisbon and Porto while saving big money on roundtrip itineraries. There are some nonstops available, too.A few housekeeping notes. These discounted fares are for basic economy seats. This means that you can only bring a carry-on bag for those fares, so if you prefer to travel with checked baggage take a look at what it will cost you to upgrade to get a free checked bag, compared to paying for a checked bag separately. Often, you’ll find it will save you money to upgrade.Want your TPG news delivered straight to your inbox each morning?
