Booking Without A Specific Destination
 

We want to fly from LAX to western Europe in business class and are seeking the least expensive fare to get there and willing to take a another flight once in Europe to get to a specific city of choice. Does anyone e know of a way to search for fares within a region rather than a specific city?

flights.google.com, search for "europe" as destination, If your dates are flexible too, you can use the Explore function to search the map for something like "two week trip sometime in the next six months".

Skyscanner will also show you options if you just type in "Europe" or "Spain" .... although not as graphically pleasing as Google Flights.
