The cheap flight is a trap.
We priced a full week, the cheapest airfare plus seven days on the ground, in 99 destinations from all 12 U.S. cities we cover, and we re-price the whole thing every day. The cities that are cheapest to fly to turn out to be some of the most expensive to spend a week in.
Everyone optimizes the flight. It's the wrong number to optimize.
A flight is a fraction of what a trip costs, usually 10 to 30 percent, and it often points you in exactly the wrong direction. So we stopped looking at fares in isolation and priced the whole week instead. The pattern that fell out is hard to unsee.
The cheapest flight on the board is a trap
The single cheapest flight in our data goes to Las Vegas: about $109 round-trip from a typical U.S. city. By airfare alone, Vegas wins everything.
Then you land. Vegas runs about $130 a day. Seven days of that is $910, and the trip you thought was the cheapest on the board is the tenth-cheapest week, behind nine places most people assume cost more. It's a pattern, not a one-off:
| Cheap to fly to | Flight | A week, all in | Rank by week |
|---|---|---|---|
| Las Vegas | $109 | $1,019 | 10th cheapest |
| Orlando | $138 | $1,188 | 25th |
| Cancún | $298 | $1,068 | 15th |
| San Diego | $240 | $1,220 | 29th |
| Nassau | $292 | $1,342 | 42nd |
Every one of these is cheap to reach and expensive to be in. The flight told you to come; the week is where the money went.
The flights that look expensive usually aren't
Now the other direction. The four-figure flights that scare people off often lead to the cheapest weeks of all, because the places they go to cost almost nothing once you're there. A week in Chiang Mai involves a roughly $1,200 flight and still comes in around $1,450, on a $40-a-day budget. Kathmandu runs $35 a day. The expensive flight buys you into a cheap life.
And occasionally you get both. Mexico City is a ~$290 flight and a $742 week, the third-cheapest trip in the entire dataset. The cheap flight and the cheap week almost never line up, which is exactly why nobody expects the few times they do.
Why this happens: the number nobody compares
The daily cost of being somewhere ranges from about $35 a day to $280 a day across our cities, an eight-fold spread. Over a week that's a swing of roughly $1,700, far bigger than the gap between most airfares. The ground cost is the larger lever, and it's the one no flight search shows you. You can see every fare to the dollar and have no idea the week behind it costs twice as much in one city as another.
The matchups that sound wrong and aren't
Put the two halves together and the map redraws:
A week in Medellín ($835) costs less than a week in Las Vegas ($1,019), even though the flight to Medellín costs more than four times as much. A week in Mexico City ($742) beats a week in Cancún ($1,068), same country, the city is cheaper than the resort. Mérida beats Cancún by nearly $400. And a week in Bangkok comes in under a week in Honolulu from every U.S. city we checked. We keep the receipts on each of those.
The cheapest weeks aren't where the cheap flights go
The ten cheapest weeks in our data are a near-clean sweep of Latin America: Guatemala City ($638), Mérida ($682), Mexico City ($742), Bogotá ($764), Oaxaca ($781), Medellín ($835). Not one of them is where the $100 flights go. The cheap weeks are simply where the cheap days are.
At the far end sit the Maldives ($3,250, on $280 a day), the long-haul Pacific (Auckland, Sydney, Melbourne, where the flight and the day rate both bite), and the high-daily Western capitals like Reykjavík ($200/day) and London ($180/day). Expensive to reach, expensive to be in, no relief either way.
So
The lesson isn't "fly far." It's: stop optimizing the flight and start pricing the week. The fare is the part everyone obsesses over and the part that decides the least. Add the seven days behind it and your budget reaches a lot further than the flight search led you to believe, just usually not where you were looking.
That's the whole idea behind DashAway: tell us your city and what you can spend, and we'll show you where a week actually fits.

"A week, all in" = the cheapest round-trip airfare we've recorded (origin-agnostic figures use the median across the 12 cities) plus seven nights at the destination's estimated daily cost, lodging, food, local transport, a normal day. The daily costs are our estimates, not invoices; the airfares are real but directional, the cheapest we've seen rather than a quote you can book this second. Figures are from June 2026 and they move, that's the point of re-pricing daily. We don't price hotels or activities individually, and we don't sell flights; every fare links out to Google Flights.
