Fly to multiple cities in Europe for as little as $453 round-trip

Attend a port wine tasting in Porto, Portugal, or try a pastry at the Cafe Central in Vienna.

It would normally cost a lot to travel to places like Porto and Vienna. However, airlines are offering marked-down flights to cities across Europe, with the cheapest flights starting at $453 round-trip.

From the U.S., you can primarily fly to Europe from Atlanta, Charlotte, Dallas, Miami and Minneapolis. But the options in Europe are almost endless.

Beyond Porto and Vienna, there are cheap flights to Copenhagen, Stockholm, Berlin, Munich, Dublin and Helsinki, to name a few.

The travel dates for these deals are from February through May and October through December. These fares are only expected to last for a couple of days.

Sample flights

Even though availability is primarily limited to just five U.S. cities, you can fly to nearly anywhere in Europe with this deal — cities like Berlin, Copenhagen and Stockholm are all on the map.

Here are some standout flights:

• TAP: Miami International Airport (MIA) to Josep Tarradellas Barcelona-El Prat Airport (BCN), starting at $453 (includes a layover in Lisbon, Portugal).
• Air France: MIA to Copenhagen Airport (CPH), starting at $477 (includes a layover in Paris).
• Icelandair: Minneapolis-Saint Paul International Airport (MSP) to Dublin Airport (DUB), starting at $516 (includes a layover in Reykjavik).
• Air France and Delta: Hartsfield-Jackson Atlanta International Airport (ATL) to Vienna International Airport (VIE), starting at $579 (includes a layover in Paris).
• American: Charlotte Douglas International Airport (CLT) to Munich International Airport (MUC), starting at $578.
• Delta: Dallas Fort Worth International Airport (DFW) to Edinburgh Airport (EDI), starting at $580.

We recommend searching through Google Flights to find your ideal dates and then booking your flights on the airline's website, since airlines are more dependable if your flight is canceled, delayed or experiences a booking change.

For a Dec. 4-11 trip from Atlanta to Vienna, Air France and Delta both offer flights priced at $579. The Air France flight departs at 5 p.m., and the Delta one takes off at 11 p.m. Both options include a layover in Paris.

If you select the Air France flight, the carrier has a return flight that leaves Vienna at 6:15 a.m.

The flights in this deal are only basic economy fares. Air France's most basic fare, known as Economy Light, allows passengers to bring a carry-on and personal item and lets them make changes to their ticket.

However, passengers flying with Air France's Economy Light must pay a fee for seat selection, and the fare does not include checked baggage.

If you check one bag, it will cost $160 round trip ($80 each way).

Seat selection starts at $27.54, but can cost as much as $75.60 if you sit in the exit row. The more expensive seats tend to be at the front of the aircraft and have more legroom.

Bottom line

These deals to Europe are not always easy to come by. It's typically more expensive to fly to Europe during the warmer months, so it's definitely worth booking these tickets while they're still available.

Since the beginning of the year, airlines across the board have been slashing fares to Europe, but these low fares won't last long — flights are certain to fill up.
