5 Underrated European Cities with Surprisingly Cheap Flights

krakow

If you’re planning a trip to Europe, you don’t have to overpay for flights just to land somewhere worth visiting. While most travelers default to London, Paris, or Rome, there’s a whole tier of European cities with lower fares, fewer crowds, and just as much to do. This guide breaks down five underrated destinations where the flights are actually affordable — and what to expect when you get there:

I’d check Porto, Bologna, Valencia, Kraków, and Riga before booking London or Paris. The article’s round-trip fare benchmarks run from $426 to $750, depending on the city, season, and U.S. departure airport – not live quotes or guaranteed prices.

Here’s how I’d narrow the choices:

  • Porto: River views, port wine, and trips to the Douro Valley.
  • Bologna: Pasta, historic streets, and rail trips around northern Italy.
  • Valencia: Beaches, paella, and metro access from the airport.
  • Kraków: Historic sites, a walkable center, and nearby memorial visits.
  • Riga: Architecture, markets, and beach trips to Jūrmala.
 

Quick Comparison

CityRound-trip fare benchmarkTrip focus
Porto$426–$650Food and wine
Bologna$500–$750Food and rail trips
Valencia$450–$700City and beach
Kraków$450–$700History
Riga$500–$750Architecture and the Baltics

My rule: compare the total trip cost, not just the ticket. Use the same dates and baggage allowance, then add airport travel, transfers, and any overnight layovers. Check whether connections share one ticket, too. Once the numbers work, I’d set fare alerts – through Dollar Flight Club or another service – rather than assume a smaller city is always cheaper, or use Skyscanner to verify the price difference.

At a Glance: Flights, Prices, and U.S. Departure Airports

Use these fares as benchmarks for cheaper alternatives to London and Paris. Round-trip fares to secondary cities range from about $350 to $570, compared with $1,700 to $2,100 for London and Paris during peak periods. These prices are benchmarks, not guarantees.

Before booking, compare fares using the same departure airport, dates, baggage allowances, and total travel time.

The next sections look beyond airfare at what each city offers, starting with Porto – one of the strongest options for getting more for your travel budget.

porto

1. Porto, Portugal

Fare Drivers and U.S. Departure Airports

Competition among low-cost carriers helps keep Porto fares low, though the cheapest transatlantic deals depend on your route and dates. Start with Newark (EWR), then check JFK and BOS. Newark often costs $100–$200 less than JFK on international routes. From MIA or IAD, check connecting flights, too. Any savings need to hold up after baggage fees and connection costs.

Flight Prices Compared with London or Paris

Round-trip Porto fares have dropped to $426–$650, compared with about $1,700–$2,100 for peak-summer flights to London or Paris.

What to See and Nearby Trips

Porto is a good fit for food-and-wine travelers. Walk through Ribeira for Douro River views, then cross to Vila Nova de Gaia’s port-wine lodges. Leave time for São Bento Station’s blue-and-white tile murals.

For a side trip, head to the Douro Valley for wine country, Braga for religious landmarks, or Guimarães for Portuguese history. After pricing neighborhoods and day trips, compare airport transfer costs before booking.

Connections, Baggage, and Airport Transfers

Take the airport metro to keep arrival costs down. Flying into Porto rather than Lisbon can save $500 or more during peak periods. If Lisbon has the cheaper flight, factor in the trip to Porto: train tickets cost about $30–$80, and the added travel time and rail costs may cancel out the airfare savings.

From the West Coast, booking a separate flight to an East Coast gateway such as JFK or BOS can save more than $1,200. Check baggage fees before booking an itinerary that uses multiple airlines.

bologna

2. Bologna, Italy

Fare Drivers and U.S. Departure Airports

Bologna can cost less for travelers who want to visit Italy without paying Rome or Milan prices. Check JFK, EWR, BOS, ORD, and PHL for connecting flights to Bologna (BLQ) through hubs such as London, Paris, or Frankfurt.

Competition from Rome and Milan helps keep Bologna’s fares in check: travelers can fly into either city and take a train. But Bologna is the better deal ONLY when the total trip costs less.

Flight Prices Compared with London or Paris

Typical round-trip fares are $500–$750 to Bologna, compared with $600–$950 to London or Paris. Peak summer 2026 fares to London and Paris reach $1,700–$2,100 round trip. Compare the full trip cost, including baggage, and weigh the time spent connecting.

At the right fare, Bologna offers a central base, good rail links, and plenty of reasons to plan your days around food.

What to See and Nearby Trips

Follow Bologna’s UNESCO-listed porticoes to Piazza Maggiore, then wander through the historic university district. Make time for tortellini and tagliatelle al ragù. The Two Towers, Asinelli and Garisenda, are signature sights, though you should check current access before visiting.

Head to Modena for a balsamic-vinegar side trip or Parma for prosciutto and Parmigiano Reggiano. Florence, Venice, Milan, and Ravenna are reachable by train, but not all make easy day trips.

Connections, Baggage, and Airport Transfers

Before booking, compare layover length, baggage fees, and the Marconi Express fare. Bologna works best for Emilia-Romagna and northern Italy. If you’re heading south, the extra rail time can wipe out your savings.

valencia

3. Valencia, Spain

Fare Drivers and U.S. Departure Airports

For a trip to Spain without Madrid or Barcelona prices, check Valencia. Outside peak summer, airlines often discount connecting flights to Valencia (VLC). Watch fares from JFK, EWR, MIA, BOS, and ATL. Competition between airline networks can make the total ticket price lower than flying into a major hub.

Flight Prices Compared with London or Paris

Use $450–$700 round trip to Valencia as your benchmark, compared with $550–$900 for London or Paris.

What to See and Nearby Trips

Valencia pairs affordable flights with plenty to do. Visit the City of Arts and Sciences, walk through Turia Gardens in a former riverbed, and spend time at Central Market, in the old town, and on the beaches. Try paella in the place where it originated.

Spring or early fall offers a good balance of weather and cost. March’s Las Fallas brings crowds and higher hotel prices, though. Valencia is a good fit if you want beach access, solid transit, and a lower arrival cost than Spain’s bigger gateways.

Connections, Baggage, and Airport Transfers

If Madrid has the cheaper airfare, budget another $35–$80 each way, plus 3–5 hours for onward train travel and transfers. A ticket all the way to VLC can cost less than a flight to Madrid plus separate train tickets. Valencia Airport has direct metro access to the city center.

4. Kraków, Poland

Fare Drivers and U.S. Departure Airports

Search JFK, EWR, ORD, BOS, and IAD for one-stop flights to Kraków (KRK), typically through major European hubs. Competition from low-cost carriers within Europe helps keep some one-stop fares lower. Once you arrive, you’ll find a walkable center, major historic sites, and easy rail access.

Flight Prices Compared with London or Paris

For shoulder-season trips, budget $450–$700 round trip to Kraków, compared with $600–$950 to London or Paris on similar dates.

What to See and Nearby Trips

Kraków packs plenty into its walkable historic core. Visit Main Market Square and Wawel Royal Castle, and learn about Kazimierz’s Jewish heritage. Approach Auschwitz-Birkenau as a memorial, not a casual sightseeing stop. Book ahead and read the site guidance before your visit.

For a nearby trip, head to Wieliczka Salt Mine to see its underground salt-carved chapels. You can also take Poland’s rail network to Warsaw or Wrocław.

Connections, Baggage, and Airport Transfers

Take the airport train into the city center to keep arrival costs low.

riga

5. Riga, Latvia

Fare Drivers and U.S. Departure Airports

Riga can offer a lower-cost route to the Baltics than major European hubs, without the expense of a London or Paris connection.

Watch JFK, EWR, BOS, ORD, and IAD for one-stop fares through Stockholm (ARN). Prices fluctuate more than fares to major hubs, but Riga can still come out cheaper.

Flight Prices Compared with London or Paris

For shoulder-season deals, aim for $500–$750 round trip, compared with $600–$950 to London or Paris.

What to See and Nearby Trips

Riga suits architecture lovers and travelers focused on Latvia or the Baltics. Walk past Art Nouveau buildings and through the UNESCO-listed medieval Old Town, then browse Central Market’s five former zeppelin hangars. Save a day for Jūrmala’s sandy beaches and wooden architecture.

Connections, Baggage, and Airport Transfers

Take Bus 22 to the city center. Before booking, add transfer expenses, baggage fees, and any overnight layover hotel costs to the fare, and allow enough time for connections. If you’re heading to Tallinn or Vilnius next, check schedules and journey times, too.

Check the Total Trip Cost Before Booking

When comparing these five routes, learn how to find cheap flights and look beyond the airfare. Check the same dates and trip length from two U.S. airports you can reach, such as JFK/Newark, BWI/Dulles, or Fort Lauderdale/Miami. Count the round-trip cost of getting to each airport, too.

Keep baggage and seat choices the same across comparisons. Before booking, add airport transfers, rail fares, and any overnight lodging or meals.

Hypothetical comparison: A $480 fare plus $140 in transport and lodging totals $620. A $590 flight arriving nearer your intended destination costs $30 less, assuming other fees are equal – and avoids the extra detour.

Check whether connections are on one ticket. If you miss a connection on a single ticket, the airline will usually rebook you. With separate tickets, a delay can void your next leg and wipe out the savings. Leave plenty of time between flights – or plan an overnight stay – and include that cost in your comparison.

Use London and Paris only as benchmarks. A cheaper gateway makes sense only if the onward travel still fits your route.

Once you’ve worked out the full trip cost, set alerts for these routes to catch the next price drop.

FAQs

How far ahead should I book these flights?
