Why Americans Lose $1,000 on Average From This Simple Booking Error

One small planning choice—locking weekend-to-weekend roundtrips into and out of the same city—quietly loads your trip with higher airfares, pricier hotel nights, and needless backtracking. Shift the dates and the route, and a couple or family routinely keeps hundreds—often around a thousand—of dollars in their pocket.

Picture it: you plan a Europe loop—fly to Rome, train north to Florence and Venice, then hop to Paris. You book the flights first, roundtrip to Rome, Saturday to Sunday. The dates look tidy. Then the penny drops: you have to backtrack to Rome to fly home, your Saturday and Sunday flights were the most expensive days of the week, and the weekend hotel nights you just locked are the priciest nights of the stay. None of this is bad luck. It’s the result of one habit.

This guide shows you exactly how that single habit—weekend-to-weekend, same-city roundtrip—drives costs up, and how to flip it: fly midweek, use an open-jaw (multi-city) ticket, and sleep midweek in your most expensive city. The steps take minutes. The savings compound.

The error, defined simply

It’s two moves rolled into one: booking roundtrip to the same city when your itinerary runs in a straight line, and setting those flights on peak weekend days because the calendar feels clean.

Why it’s costly is straightforward. Weekend departures and returns tend to price higher than midweek choices; an open-jaw (into one city, out of another) often costs similar to a roundtrip, while saving you the train or plane backtrack; and European hotels commonly price weekends above weekdays. Do all three the “default” way and you stack three premiums on the same trip. Flip them, and you stack savings instead. The fix is not exotic—it’s one search mode and two flexible dates.

Where the money leaks—line by line

Start with flights. Multiple 2025 analyses show that midweek departures beat Sunday by a healthy margin on international routes. One major report found Thursday departures save about 15% versus Sunday, while another showed Tuesday/Wednesday patterns lopping significant dollars off Europe tickets. For a typical transatlantic fare, that’s roughly $150–$200 per person on the outbound alone; time both outbound and return midweek and the effect doubles. In a party of two or four, it adds up fast.

Then hotels. City properties frequently run weekend rates 15–20% higher than weekdays. If your “headline” city is Paris, Florence, or Vienna, dropping your two most expensive nights onto Tuesday/Wednesday instead of Friday/Saturday can shave triple-digit dollars off the same rooms.

Finally, the backtrack. If you fly in and out of Rome but finish in Venice or Paris, you pay to get back to Rome. That might be a high-speed train (€30–€90 per person on sale on Italy’s trunk routes) or a one-way flight (which on weekends can be pricey). Add transit time, an extra meal on the road, sometimes another hotel night, and airport transfers in the wrong city. On a couple’s trip, the all-in “oops” commonly lands in the low hundreds; for a family, it routinely cracks four figures.

Put those three together and you see why the “clean calendar” roundtrip is anything but clean on your wallet: higher weekend fares, weekend hotel premiums, and avoidable backtracking.

The two-switch fix that stops the bleed

You don’t need tricks. You need two switches: open-jaw and midweek.

Open-jaw (also called multi-city) means you fly into City A and home from City B. If your route is Rome → Florence → Venice → Paris, you search U.S. → Rome and Paris → U.S. on one ticket. Modern fare construction often prices this similar to a classic roundtrip, and you remove an entire leg (and its costs) from your plan. The effect isn’t subtle: you reclaim a day, avoid an extra transport bill, and spare yourself the stress of racing back to your starting point.

Midweek simply means depart and return on cheaper days (typically Tue/Wed/Thu outbound and Tue/Wed inbound). Those days pull fares down and move your priciest hotel nights away from peak weekends. The combo is what matters. Open-jaw kills backtracking, midweek lowers base prices, and midweek hotel nights keep the room budget calm.

A conservative savings picture (so you know this isn’t hype)

Let’s price the change with cautious assumptions for a one-week Europe trip:

• Flights: You and a partner shift from Sunday/Sunday to Wed/Wed. Recent 2025 data suggests ~15% savings on international fares when flying midweek vs Sunday. If your roundtrip was $1,100 per person, 15% off is $165 each. Outbound and inbound both midweek? Call it ~$330 saved for two.
• Hotels: Your target city’s average nightly rate is $160, and weekends run ~15–20% higher. Moving two heavy nights to midweek saves ~$50–$60 total per night across two nights—call it $100–$120 back.
• Backtrack avoided: Rome↔Venice high-speed train is often €30–€90 per person each way if bought smart; Eurostar London↔Paris often from ~£39–£71 each way on sale; intercity France €40–€80 isn’t unusual with advance purchase. Conservatively, avoiding a single backtrack leg for two people saves $120–$200 (often more), plus local transfers you no longer need ($30–$60).
• Intangibles that still cost money: Meals and time lost during the backtrack, the chance you’ll need an extra night near your original airport to make a morning flight, and the risk you buy a pricier one-way if you left this to the last minute.

Even with restrained numbers, a couple is commonly ahead $600–$800. Add a third or fourth traveler and you sail past $1,000 without trying. And if your original plan stacked both Saturday departure and Sunday return plus same-city roundtrip, the gap often widens.

What’s doing the work: midweek flights cut the fare, midweek nights trim hotel ADR, and open-jaw deletes an entire leg of transport. Three independent levers, one simple result.

The 10-minute booking flow (steal this)

Open your usual flight search and do this in order:

1. Sketch the route you’ll actually travel. If your map is A→B→C, your flights should be into A, out of C. That single thought fends off so many headaches.
2. Search multi-city (open-jaw) before roundtrip. Enter Home → City 1 for the outbound and City 2 → Home for the return. Set only a month first to see the price calendar and identify cheap midweek days.
3. Use the date grid/price graph. Drag your depart/return a day or two. You’ll see the fare drop on Tue/Wed/Thu in most lanes, especially versus Sunday. Lock the best pair you can—often out Wed, back Tue is a sweet spot.
4. Anchor the priciest city midweek. If one city has a noticeably higher hotel average, arrange your nights so your Fri/Sat happen in the cheaper stop and your Tue/Wed in the expensive one.
5. Check the backtrack math. If you’re tempted by a same-city roundtrip, price the return-to-origin transport you’d need (rail/air) and add one airport transfer. Nine times out of ten the multi-city wins.
6. Book the long legs; leave regional rail flexible. Reserve transatlantic and any sleeper/intercity you must lock. For short regional trains, buying later is often fine.

Two switches. Ten minutes. Real money.

When the “rule” bends (and how to decide)

There are reasonable exceptions. If a fare war drops one city’s roundtrip price far below everything else, a same-city ticket plus a cheap hop can win. Likewise, if your trip is a single-city stay with no onward travel, an open-jaw makes no sense. And during special events (fairs, football finals, festivals), a city’s weekend premium may spill across the whole week.

Use three questions to sanity-check: Are my flights on cheaper midweek days? Does my ticket match my route’s shape? Am I paying to undo my earlier decision? If you answer yes-no-yes, you’ve found the leak.

City patterns that make the fix even richer

Some pairings practically demand open-jaw because the backtrack is long and the weekend rates are steep.

Paris ↔ Strasbourg (Alsace): Christmas-market season pushes weekend ADR up in Strasbourg and opening weekends are crush-heavy. Fly midweek, sleep midweek in Strasbourg, and don’t backtrack to Paris just to fly home.

Rome → Venice → Paris: Italy’s north-south trunk is fast and cheap on rail, but Rome↔Venice adds hours and extra spend you don’t need. Fly into Rome, home from Paris, and let the map be linear. Midweek flights plus open-jaw here do double duty.

London ↔ Paris: Eurostar is often cheaper midweek, and weekend city hotels spike. A Wed arrival in Paris after a Tue London departure often trims both fares and ADR.

The pattern repeats everywhere: long backtracks and leisure-heavy weekends multiply your costs when you lock weekend-to-weekend, same-city plans.

FAQs that save you from second-guessing

Are open-jaw tickets really not more expensive? In many lanes they price comparable to roundtrips—sometimes better—because you’re still buying a single return with different endpoints. The advantage is you delete a leg of ground or air travel that you’d otherwise pay for separately.

Is the midweek savings real or just seasonal? Multiple 2025 data reads point to consistent day-of-week differences: Tue/Wed/Thu tend to be cheaper to fly, while Sun/Mon/Fri skew high. It isn’t every route, every week—but it’s reliable enough to design around.

How many days should I shift? Often just one does it. Move a Sunday to Saturday outbound domestically or to Thursday internationally, and pull a Sunday return to Tuesday. Even a small nudge can trigger a lower fare bucket, and it drops hotel rates with it.

What if I already booked wrong? Many economy tickets now allow free changes for a fare difference. If shifting one or two days drops the fare, you can come out even after a reprice. Hotels on flexible rates can be moved the same day you change flights. Check policies now—then press the button.

What smart travelers do differently

They don’t out-research everyone. They avoid one habit that punishes their budget. When a map runs in a line, they book in at the start and out at the end. When a calendar offers them Wednesday and Tuesday for less, they take Wednesday and Tuesday. And when a city is much more expensive on weekends, they sleep there midweek and smile at the bill.

If you’ve been donating money to the “clean calendar” myth, you’re one ten-minute search away from ending it. The trip doesn’t change. The price does. Open-jaw, midweek, linear routing—that’s the whole playbook.
