My family just flew to three European countries and home again for $149 per person total

The one "catch" to travel hacking? It's a complicated, strategic long game that takes time and effort to learn. But it's totally worth it. The basic gist is that you maximize credit card sign-up bonuses to accumulate transferable credit card points or loyalty points/miles with hotels and airlines, all without spending any more money than you normally would. Then you learn how to redeem those points for travel, which makes them way more valuable than simply getting cash back.

I wrote an overview of how the game works in a previous article (which you can read here), but I figured a real-life example is the best illustration.

For this trip to Europe, I transferred 362,500 Chase Ultimate Rewards credit card points to United Airlines. (My husband and I have accumulated over 1.2 million points and miles in the past year and a half, so this trip was barely a third of our points.) That's what all of our flights to, from and around Europe cost, plus one more flight paid for with Southwest points to get all the way home. The taxes and fees for all flights came out to $149 for each of us.

Our original itinerary was actually US > London > Athens > Tel Aviv > US, but obviously the Israel plans changed when the war began. We switched from Tel Aviv to Vienna for our music-loving kids just a couple of weeks before we departed. The flight from Vienna back to the US cost fewer points than the Tel Aviv to US flight, which made it so our added Athens to Vienna flight was covered by points we'd already spent. (We'd originally booked a one-way cash flight from Athens to Tel Aviv. That got refunded when the flight was canceled.) And thanks to United's Excursionist Perk, our London to Athens leg also cost us zero points—we only paid taxes.

So what you see here are the fees we paid out of pocket for three flights—Spokane to London, London to Athens, and Vienna to Chicago (where we stopped to see family and friends for a few days on our way home). The Oct 15 "date of purchase" was actually the date we changed our Tel Aviv flight to Vienna—we purchased the original tickets months ago.

As you can see, the fees for these flights were $112 per person:

Here are the taxes and fees for the Athens to Vienna leg we added after the Israel changes, which were $31.40 per person:

Finally, to get back to Spokane from Chicago, we booked flights on Southwest. We have a ton of Southwest Rapid Rewards points accumulated from playing the game as well as two Southwest Companion Passes, which means two of our kids traveled with us for free (only paid fees on their flights—no points needed). So we paid 14,345 Southwest points x 3 (43,035 points total) and the fees were just $5.60 each, which brings us to our grand total of $149 per person.

To reiterate, we didn't pay anything beyond our normal spending for the points we used to get these flights. We just strategically utilized new credit cards for all of our expenses every few months. Accumulating points is actually the simpler part of the game. Figuring how to find the best redemption deals for the points is where it gets complicated and the real work comes in.

It's not like I just went on the United website, put in our dates and destinations, transferred the points and got the tickets. I spent many hours poring over different airline websites and different city combinations and dates to see where the best deals were. (We weren't tied to particular cities or dates other than our religious pilgrimage to Haifa, which didn't end up happening anyway.) It took a lot of time to find these tickets for the price we did, but again, totally worth it to save thousands of dollars.

If there weren't as many of us, we could also have gotten hotels on points, but with a family of five it was more affordable to book Airbnbs where we were Europe. So it's not like this vacation cost us nothing—we still had accommodations, public transportation, a car rental in Greece for exploring outside of Athens for a few days, food (pretty cheap in Greece, more expensive in the U.K. and Austria), and any museums, attractions and events we enjoyed.

But getting the flights for a song enabled us to do the rest. The cash price for the exact same flight itinerary would have cost between $6,000 and $9,000 for the whole family, especially since most of our flights were direct and at desirable times. Even if we were to see the 362,500 Chase points we used for their straight cash back value ($3,625), we still got a good deal. But those points didn't cost us anything. And our family got to take the trip of a lifetime. Travel hacking for the win.
