Best site to find open jaws flights

It's basically the same process--you select "multi-city" and then plug in the airport codes.
I usually start with Kayak just for ease of searching but purchase directly from the airlines.

Google Flights works great for me.

I use https://matrix.itasoftware.comwhich is the search engine for Google Flights in a different format. It's great for searching flights but tickets cannot be purchased there.

I had a very negative experience purchasing tickets thru a big international ticket consolidator. I now go directly to the airline to purchase flights, and I always pay with a credit card.

Like they say, click on the multi-city flight which is open jaw. Having to backtrack to the first city you land at can be very expensive.

It is the same as buying any other ticket. Just check the box for multi-city when you start the process. There are no special sites for open jaws. OJs are just regular type of tickets. What do you think you will miss? You don't find open jaw ticket, you just book them. Any trip can be an open jaw. About 75% or more of our trips are open jaw because it is generally cheaper. Which search engine do you normally use?

Do you have an airline preference? If so start on that website, if not, go with one of the search engines mentioned here but then go to the airline website to book.

And agree...what do you think you might miss?

Thanks for the advice! I think I was concerned about additional costs. I'm not used to paying for seats! I think my biggest problem is my crappy wifi! I have used kyak and Google flights.

we always have the best luck with the actual airline website under 'MULTICITY' --- Delta or American is usually our preference and we usually get the best price on Delta.

You'll be paying extra to choose your seat no matter if it's open jaw or not--that's just how it is these days!
The thing you do need to be careful about is reading the difference between the different fare types: "basic economy," "economy light," etc. (every airline seems to have a different naming system, adding to my confusion.) Unless you are purchasing quality insurance separately, you may want something that you can change without major penalty in case something comes up.

Thoughts:

Kayak lists all airlines, Google flights excludes some discount airlines like Condor.

American carriers still do not charge for seat selection unless one picks basic economy (one step below coach). AFAIK all European airlines charge for seats.

Search sites can find cheaper fares than can be found at the actual airline website, but be sure to click an airline website at the bottom of the search page, you roll over to buy there.

I just searched for a random flight to Europe on Google Flights, and a Condor flight showed up as the best option.

Condor was not showing recently but now it is.

Discount airlines don’t always show up.

Edit: Kayak is much more powerful, can select for checked bags, and various toggles can be made inside the fare on Kayak with explanations as to the difference between economy light, economy basic, economy basic plus, etc, to refine desired fare before rolling over to the airline website. On Kayak can also exclude third party website only fares, and phone only fares,

Skyscanner is my go-to site.

I will check reversing the open jaw cities and changing the flight dates +/- a few days to look for best price and flights.

Thank you!👍👍🙂

On the United Airlines site, you click on "Advanced Search" to find multi-city.

Another strategy to consider would be to book your main flight to Europe as a round trip on any of the major airlines and, once arrived at your gateway city, take advantage of cheap flights within Europe on one of the low-cost carriers (RyanAir, etc.) to continue on to other destinations that appeal to you.
The service will be spartan but the flights are quite cheap (and usually of short duration). Might be a cost-effective alternative to a classic multi-destination itinerary.

This is an excellent strategy IMHO. One thing add in 1 to 2 days at the gateway city before taking the flights on the low-cost carriers. More than likely you will be on separate tickets if the inbound flight to your gateway city is delayed or canceled there will be issues. Better yet book the low cost carriers after you arrive.

I have done what Robert suggested and a variation. I booked flight to mayor cities where the competition for flights might be higher just to get cheaper tickets and then flown to my final destination the same day of arrival. Of course I always compare the full length price to this solution for both price and flight duration.

Thank you Va from Va!! And all.

And if the information you get from a multi-city search is too much to absorb at once, you can always search for each flight separately. Once you find what you like, you can book as one trip
