If an itinerary found using ITA Matrix is still available, you should be find it using Hipmunk as well. Although Hipmunk doesn’t have a tool that specifically searches itineraries using ITA fare codes, you can use the tools available in our flight product to narrow down your options until you locate the one you’re searching for.
Start by running a basic round trip flight search. For complex multi-city searches, make sure to select the “Multi-city” option above the search bar.
On the results page, we suggest using the “airline” filter to find the correct carrier and “time sliders” to narrow down results by time. For help using our flight results tools, visit our article “Navigating through flight results/Booking a flight”
Once you narrow down the flight options, you can hover your mouse over each flight bar to find the specific one you’re looking for. Continue this process of narrowing down results for each leg until you find your entire itinerary.
