The report looked not only at one-time deals but at the overall volume of low airfares available for a given city. The full list of cheapest European cities to fly to from the U.S.:
Paris (average $552 round trip)
Dublin (average $554 round trip)
Barcelona (average $525 round trip)
Milan (average $532 round trip)
Rome (average $551 round trip)
Madrid (average $518 round trip)
Copenhagen (average $555 round trip)
Amsterdam (average $553 round trip)
Zurich (average $553 round trip)
Stockholm (average $556 round trip)
“We chose to rank based on the volume of economy deals and average price because — while the price of the single best deal we found to one city might be lower than the price of the single best deal we found to another — volume is the better indicator of a traveler’s likelihood of snagging a great price,” the report noted.
However, the report also showed that the absolute lowest price available for a ticket to Paris came in at $248 round trip, so savvy travelers can snag even lower deals. (Normal economy tickets run about $850 between major U.S. cities and the City of Lights.) Paris is an especially low-priced European destination because 19 routes serve the city from the U.S.
A notable city missing from the list: London. The main airport serving the U.K.’s largest metropolis, Heathrow, has some of the highest taxes and departure fees on the continent. That reduces opportunities for travelers to snag a low-cost ticket to Great Britain.
But even if your preferred destination city is not on the list, it’s possible to fly to the nearest “cheap city” and then take a less expensive regional flight to get you where you want to go. For example, you might get a ticket to Dublin and a regional flight to a smaller airport near London rather than fly directly there.
The Going.com report examines economy-class airfare prices from the U.S. to European cities with more than 700,000 residents. It found that factors influencing flight costs include:
the number of airports in a city
the number of airlines that serve those airports
the amount of competition on routes to and from the city
The report analyzed deals available from June 30, 2022 to July 2, 2023.
