A new website called Mindtrip Flights lets you search for flights by just describing what you want. You can say, “Find me roundtrip business flights between San Diego fo a 7 day vacation in Paris in June,” or even, “Find me the lowest business class fare betweeen San Diego and somewhere in Europe for 7 to 10 days in October.” It returns with specific itineraries after looking at all of the options.”
It essentially does what my wife – a skilled self-taught travel planner – did several months ago when she searched for flights to South Africa, but zeroed in quickly on both the both the route with the shortest travel time and then, when we asked, the route with the lowest price. Compared to our manual searches, it provided all of the options it took us several hours to find and evaluate, but also suggested splitting our ticket to get to the East Coast on a separate ticket and use a lower fare on an Ethiopean Airlines flight from DC. It also missed one low cost option using Turkish Airlines. It appears to be a good way to quickly see the options, especially when you have some flexibility and use it to compare different destinations over different dates.
