Do you have plans to travel to Europe this summer? Thrifty Traveler, a budget travel website, has put together a list of European destinations that offer the lowest airfare for flights from the United States. This is particularly useful since international airfare has gone up over 30% compared to last year, and Europe is expected to have a very busy summer for tourism. The destinations on this list offer round-trip airfare as low as $400 to $600. By flying to one of these destinations first, you can potentially save a lot of money since airfare for flights within Europe is usually inexpensive.

When it comes to finding inexpensive flight options, Spain stands out as one of the top destinations in Europe. Its location on the Iberian Peninsula in Western Europe makes it more accessible from the United States than destinations further east, with plenty of affordable flight options available. Moreover, Spain is an ideal starting point for taking budget flights to other popular European destinations like France, Italy, and Greece. As a summer destination in itself, Spain is a fantastic choice with great deals available in late August and early September for as low as $400 to $500.

Much like Spain, Portugal is a perfect springboard for reaching other European locations, with various budget airlines to choose from. Moreover, this summer, Portugal makes an excellent holiday spot with its striking beaches, lively cities, and significantly lower prices compared to other Western European destinations.
