August is usually one of the most expensive months to fly from the United States to Europe. That is why finding a transatlantic itinerary under $750 round-trip can feel like discovering a secret passage through airport pricing.
For this roundup, I focused on five iconic European destinations: Paris, Rome, Lisbon, Barcelona and London. Every price below comes from a currently indexed flight-search or airline page. Rather than inventing a “usual price,” I compared the lowest listed fare with a more expensive currently available alternative on the same route whenever the source showed one.
Prices can change quickly, so readers should click through and re-check before booking. Google Flights and fare-comparison sites also recommend flexible dates and price alerts when searching for summer travel.
1. Chicago to Rome from $686 round-trip
For travelers dreaming of pasta, piazzas and late-night walks past ancient ruins, this is one of the strongest August Rome deals currently listed here. A Chicago-to-Rome round-trip itinerary is available from $686, with an example departing August 3 and returning August 12.
The same search page showed nonstop options from $736 and another August itinerary reaching $1,123. That makes the lower fare particularly appealing for travelers willing to accept a connection.
Why it stands out: Rome in August is famously busy, so staying under $700 round-trip from a major US hub is notable.
2. New York to Paris from $733 round-trip
Paris is often one of the easiest European cities to reach from New York, but August can still be costly. A currently listed itinerary starts from $733 round-trip.
The same fare page showed nonstop options from $733 on some dates, but other options rose to $837, creating a potential $104 difference depending on which itinerary travelers choose.
Why Paris works: New York has multiple airport options, including JFK and Newark, which can create more price competition than many other US departure cities.
3. Boston to Lisbon from $657 round-trip
Lisbon remains one of Europe’s most appealing city-break destinations, especially for travelers who want Atlantic views, tiled streets and excellent food without Paris or London-level prices.
A Boston-to-Lisbon round-trip itinerary is listed from $657. The same route showed nonstop fares from around $1,026, creating a potential saving of roughly $369.
Why it is extraordinary: That is a substantial difference for a route that is especially popular during peak summer.
4. Miami to Barcelona from $480 one-way
Barcelona is one of the most in-demand Mediterranean destinations in August, making an economy option from $480 one-way from Miami especially worth watching.
The same search page listed nonstop fares from $632, so this option is about $152 cheaper.
Why Barcelona: It combines beach days, architecture, nightlife and easy train connections to other Spanish cities.
5. Miami to Barcelona premium economy from $835 one-way
For travelers who do not want to arrive in Barcelona feeling completely defeated by a long-haul flight, this premium economy option is interesting.
A Miami-to-Barcelona premium economy itinerary is listed from $835 one-way, while nonstop premium economy options begin around $1,166. That is a difference of approximately $331.
Why it is useful: Premium economy can offer more space and comfort without the business-class price jump.
6. New York to Paris from $325 one-way
For travelers building an open-jaw itinerary, combining separate one-way tickets can sometimes create more flexibility than a standard return booking. A New York-to-Paris economy fare is listed from $325 one-way for August.
Best for: Travelers who want to fly into Paris and return from another European city, such as Rome, Lisbon or Barcelona.
7. Washington, D.C. to London from $730 round-trip
London is rarely a bargain in August, making this Washington-to-London fare one of the most interesting transatlantic deals currently available.
A Washington Dulles-to-London Heathrow round-trip itinerary is available from $730, with one-stop flights. On the same search page, nonstop itineraries start from $849, while several August dates climb to $1,227.
That means flexible travelers could save as much as $497 simply by accepting a connection.
How to use these flight finds
The most important thing to remember is that these are not “book next year whenever you feel like it” prices. They are live or recently indexed fares, and availability can disappear fast.
Flight-comparison sites note that prices refresh frequently, and popular summer routes can change substantially based on the date, airport and number of stopovers.
For the best chance of matching these prices, try searching for Tuesday-to-Thursday departures, comparing multiple nearby airports, accepting one stop where reasonable and using fare alerts.
For New York, that may mean checking JFK and Newark. For Miami, compare Miami and Fort Lauderdale. For Washington, consider Dulles, Reagan and Baltimore where relevant.
More remarkable bargains in this list include the Boston-to-Lisbon fares from $657, the Chicago-to-Rome return flights from $686, and the Miami-to-Barcelona one-way option from $480.
None of them are “cheap” in the ultra-budget sense, but for peak August travel from the United States to some of Europe’s most famous destinations, they are worth serious attention.
Prices were checked against currently indexed fare-search pages on July 20, 2026. Airfares are dynamic, and the exact itinerary may change or disappear before publication or booking.
Hope you found this useful. Happy summer ahead guys! 🙂
