Why I Almost Never Book Roundtrip Flights (And Why You Might Want to Stop, Too)
Why I Stopped Booking Roundtrip Flights
For years, I assumed booking a roundtrip flight was simply how travel worked. Pick your destination, choose your return date, and call it a day.
Now, I rarely book roundtrip tickets.
Whether I’m paying cash or redeeming points, I almost always book two separate one-way flights instead. It isn’t because I’m trying to be clever or because I’m constantly chasing airline deals. It’s because booking one-ways gives me flexibility that a traditional roundtrip often can’t.
Even if you only take one vacation each year, this strategy can make planning a multi-city trip much easier.
Why I Prefer One-Way Flights
1. They make multi-country trips much easier.
Many of my trips aren’t circular.
In Spain, I arrived in Madrid and flew home from Barcelona. My goal for that trip was to focus entirely on Spain, so there was no reason to fly between cities or backtrack to where we started. A quick high-speed train connected Madrid and Barcelona, making it easy to travel across the country before simply flying home from our final destination.
During my Central Europe trip, I flew into Warsaw, traveled south through Poland, Slovakia, Slovenia, Croatia, and Bosnia & Herzegovina, before finishing in Amsterdam and flying home from there.
There was no logical way to turn that into a traditional roundtrip without wasting both time and money.
Booking separate one-way flights let me design the itinerary instead of forcing the itinerary around a roundtrip ticket.
London is another great example. Later this year, I’ll hopefully be taking my fifth flight there. What’s funny is that only two of those trips were actually to visit London. The other three simply used London as my gateway into Europe before continuing on to Germany with my family, Italy with my sister, and Paris to visit friends. Whether you’re paying cash or using points, London often has excellent flight options and makes an incredibly easy jumping-off point for the rest of Europe.
2. I Can Mix Airlines, Cash, and Points
Sometimes one airline has the best outbound flight while another has the better return.
The same is true for points.
Maybe the outbound is an incredible award redemption while the return is inexpensive enough to pay cash. Other times, one airline simply offers a much better schedule in one direction.
Booking two one-way flights lets me make those decisions independently instead of treating the trip as one giant purchase.
3. I Don’t Have to Wait Until I Know Every Detail
If I find a great outbound fare today, I book it.
I can keep researching my return later without worrying that the first fare will disappear.
The only caveat is that some countries require proof of onward travel before allowing you to board your flight or enter the country. If I haven’t finalized my departure plans yet, I’ll sometimes book a refundable ticket or choose an option that can easily be changed later.
It’s a small detail, but one that’s worth checking before you rely on this strategy.
4. My Outbound and Return Flights Have Different Jobs
One of the biggest reasons I rarely book roundtrip flights is that I don’t expect my outbound and return journeys to accomplish the same thing.
When I’m leaving for a trip, I don’t mind putting in a little extra effort to get the best flight. Living in Philadelphia, I’ll happily take an early Amtrak train to New York or Washington if it gives me access to better award availability or a nonstop flight that isn’t available from home. Larger markets like New York and Washington simply have more international airlines and more award availability, so positioning there still feels like part of the adventure.
Coming home is different.
After days—or sometimes weeks—of walking 20,000 steps, navigating airports, dragging luggage across cobblestone streets, and adjusting to different time zones, my priorities change.
At that point, I’m much more willing to pay a little extra for the simplest route home, even if it isn’t the absolute cheapest option. Sometimes that means booking a nonstop flight to Philadelphia. Other times it means choosing a single-ticket itinerary instead of piecing together multiple flights.
I recently helped my cousin plan her family’s first trip to Europe, and it reminded me that this strategy isn’t just useful for frequent travelers. Like many first-time visitors, they’re flying into London, taking the Eurostar to Paris, spending a few days there before visiting Disneyland Paris, and then flying home from Paris.
At first glance, the roundtrip flight looked like the cheaper option. But that comparison ignored one important cost: getting everyone back to London just to catch the flight home.
Once we factored in Eurostar tickets, several extra hours of travel, and the logistics of moving a group that included three children, the savings shrank to roughly $100 a ticket**.** At that point, flying home directly from Paris was the obvious choice.
The goal isn’t to save every dollar.
The goal is to evaluate the entire journey, not just the price of the flight.
The goal is to make the end of the trip as stress-free as possible.
Booking two one-way flights lets me optimize each journey independently instead of forcing both directions to serve the same purpose.
Isn’t It More Expensive?
Sometimes.
But in many markets, especially international travel, the difference is surprisingly small—or nonexistent.
Even when it costs a little more, the flexibility often outweighs the extra expense.
When I Still Book Roundtrip
Roundtrip tickets still make sense for:
- Weekend trips
- Single-city vacations
- Exceptional roundtrip sales
- Situations where the savings are significant
There’s no rule that says one approach is always better.
Final Thoughts
One-way tickets aren’t about being an expert traveler.
They’re about giving yourself more flexibility.
Instead of asking, “What’s the cheapest roundtrip flight?”, I now ask, “What’s the best way to build this trip?”
Sometimes the answer is a roundtrip ticket.
Other times it’s flying into one city, taking the train to another, mixing airlines, combining cash with points, or paying a little extra for an easier trip home.
Once I stopped thinking of my flights as one purchase and started treating the outbound and return as two separate decisions, my itineraries became simpler, more flexible, and often more enjoyable.
You don’t have to be visiting five countries or redeeming thousands of points for this strategy to work.
Whether it’s your first trip to Europe or your fifteenth, booking two one-way flights might give you more freedom than you realize.
