This week's budget trip math: Cozumel is the $304 route to price first
A $304 Miami–Cozumel fare and a $287 Miami–Grand Cayman fare sit $17 apart on the ticket and $453 apart once five nights are priced, with three more route screens showing where fall airfare stops predicting the bill.
Fare screens collected on September 29, 2026 put Miami–Grand Cayman at $287 roundtrip and Miami–Cozumel at $304 roundtrip. Five nights on the ground later, the two trips sit $453 apart: $962 on Grand Cayman against $509 in Cozumel. A budget room on Grand Cayman costs $94 a person a night; the same night in Cozumel costs $25.
Every fare below is a one-adult, roundtrip economy base fare from the U.S. airport named, so read them as price-check thresholds.
Three fare bands
The bands sort airfare only. Typical ranges are KAYAK's own range for that city pair, and every current fare was collected on September 29, 2026.
| Fare band | Route | Current roundtrip | Typical range | Why price it |
|---|---|---|---|---|
| Value corridor | Miami–George Town, Grand Cayman | $287 nonstop | $288–$379 | The cheapest ticket this week, on the route with the priciest five nights. |
| Value corridor | Miami–Cozumel | $304, one stop | $529–$686 | 43% below the route's usual floor, into the cheapest trip on the page. |
| Middle ground | Miami–Santiago, Chile | $440, one stop | $589–$904 | A quarter below the route's floor, on a routing through Punta Cana. |
| Middle ground | New York JFK–Dublin | $437, one stop | $430–$737 | Inside its own range, so this is a poor week to buy Ireland. |
| Middle ground | Miami–Rio de Janeiro | $617, two stops | $752–$1,062 | Below the floor, and the cheap routing takes 24 hours. |
| Premium window | Boston–Dublin | $441 nonstop | $413–$731 | Four dollars more than New York's connecting fare, for a 6h 06m nonstop. |
Four of those six sit below their own route range. Both Dublin screens sit inside theirs, which makes Ireland the week's clearest case of a fare that looks cheap only next to the alternatives.
Ten international fare targets
Going's July 13, 2026 ranking scores destinations 30% on average deal price, 35% on the discount off normal fares, and 35% on how often deals appeared, using deals sent between April 20, 2025 and April 19, 2026. Treat these as alert thresholds for the year: the sample deals show which airports get the deepest ones.
| Rank | Destination | Average Going deal | Sample economy deals | Use |
|---|---|---|---|---|
| 1 | San José, Costa Rica | $333 | Fort Lauderdale $185, Newark $191, Denver $222 | Sub-$200 is the historical signal. |
| 2 | Guatemala City | $268 | Houston $159, New York City $188, Las Vegas $248 | The lowest average on the list. |
| 3 | Calgary | $241 | Denver $129, Nashville $142, San Francisco $144 | Low-$100s fares still appear. |
| 4 | Montego Bay | $344 | Tampa $240, Detroit $268, New York City $278 | Mid-$200s is the target. |
| 5 | Liberia, Costa Rica | $343 | Fort Lauderdale $196, New York City $210, Los Angeles $282 | Under $300 is worth comparing with lodging. |
| 6 | Vancouver | $255 | Chicago $124, Phoenix $131, Atlanta $155 | Low-$100s is the benchmark. |
| 7 | Bogotá | $302 | Miami $238, Chicago $281, Austin $285 | Around $250 is the deal line. |
| 8 | Punta Cana | $336 | Miami $220, Chicago $240, New York City $247 | Price transfers and resort fees with it. |
| 9 | Auckland | $793 | Los Angeles $453, Miami $526, Boston $550 | Sub-$600 is the value signal. |
| 10 | Tokyo | $732 | Seattle $353, Pittsburgh $531, Denver $589 | Under $600 is the comparison point. |
The same page breaks the list down by travel month, which is the faster way to pick a window. October's cheapest international roundtrips are Calgary at $264, Oranjestad in Aruba at $347 and Providenciales in Turks and Caicos at $357, with Christiansted in the U.S. Virgin Islands as an honorable mention at $352. November holds Calgary at $269, Grand Cayman at $340, Aruba at $349 and Christiansted at $309. Grand Cayman's $340 November target sits $53 above this week's $287 screen, so that route's cheap window is already open.
Five trip screens
Each row is one traveler: the route fare plus five nights of lodging and five days of food at that destination's budget tier. Rows are ordered by the visible subtotal, which leaves out checked bags, local transit, activities, airport transfers, resort fees, and taxes and fees.
| Destination | Route and fare | Five nights on the ground | Visible subtotal |
|---|---|---|---|
| Cozumel | MIA–CZM $304 | Lodging $125 plus food $80, Cozumel budget tier | $509 |
| Santiago | MIA–SCL $440 | Lodging $200 plus food $40, Santiago budget tier | $680 |
| Dublin | JFK–DUB $437 | Lodging $150 plus food $180, Dublin budget tier | $767 |
| Rio de Janeiro | MIA–GIG $617 | Lodging $125 plus food $70, Rio de Janeiro budget tier | $812 |
| Grand Cayman | MIA–GCM $287 | Lodging $470 plus food $205, Cayman Islands budget tier | $962 |
The spread runs from $509 to $962. The ticket is the smaller half of the total on Grand Cayman alone, and its largest share on Rio de Janeiro, where airfare is 76% of the trip.
Treat the ground figures as floors. Budget Your Trip puts Cayman Islands budget travelers at $151 a day; its mid-range tier raises the same five nights of lodging and food to $1,640, which turns that trip into $1,927. Cozumel's mid-range tier puts the same five nights at $545, or $849 all in. Santiago's mid-range tier puts five nights at $670, which makes Chile's capital a $1,110 week.
Dublin is the one row where a budget day costs more for food ($36) than for a bed ($30), and five nights there come to three-quarters of the fare.
Booking timing that fits these routes
- Going's September 23, 2026 guide puts the international booking window at two to eight months ahead, the domestic one at one to three months, and peak-season international trips at four to ten months.
- January and February are the year's cheapest months to fly, with September and October the strongest runners-up.
- Fly Tuesday, Wednesday or Saturday where your plans allow. The day you buy barely moves the price, and Going cites Expedia's 2026 air-hacks data showing a Tuesday domestic departure about 14% cheaper than a Sunday one.
- Lead times differ by route. KAYAK's screens put the savings point at 11 weeks for Miami–Grand Cayman, about 14% below a last-minute fare; 23 weeks for Miami–Santiago, 21%; 8 weeks for Miami–Rio de Janeiro, 20%; 8 weeks for Boston–Dublin, 15%; and 25 weeks for New York JFK–Dublin, 11%. This week's Miami–Cozumel page printed no lead-time figure.
- Each route has its own cheapest month. January is cheapest on four of these six routes: Grand Cayman, 17% below the route average; Cozumel, 20%; New York JFK–Dublin, 28%; Boston–Dublin, 30%. May is cheapest for Santiago, 17% below, and March for Rio de Janeiro, 16%.
- Do not wait for a last-minute drop. Going calls it the Bargain Bin Trap: prices usually climb in the final three weeks before departure. Decide your pull-the-trigger number before you start searching.
- Set alerts in Going, Google Flights, KAYAK or Skyscanner and use the ten-target table above as your threshold, since a fare only matters if you see it while it lasts.
- If you book directly with an airline at least seven days before departure, the U.S. Department of Transportation requires either a 24-hour fare hold or a penalty-free cancellation within 24 hours. The airline chooses which, and the rule leaves online travel agencies outside it. Read the rule.
Route of the week: Cozumel
KAYAK's September 29 screen found $304 roundtrip on Viva, one stop each way in Monterrey, for a November 7–15 itinerary. That number carries two facts worth separating. Against a typical range of $529–$686, $304 sits 43% below the route's usual floor, the deepest discount on this page. The routing to get it takes 24 hours 43 minutes on the way down and 21 hours 14 minutes on the way back, and American's nonstop, on a route that averages 2h 03m, is $592 for November 10–17. The $304 buys two days of travel; the $592 buys two short flights.
On the ground, Budget Your Trip's Cozumel page, updated August 10, 2026, puts budget lodging at $25 a person a night in double occupancy and budget food at $16 a day. Five nights of both come to $205, so the visible subtotal lands at $509, the cheapest of this issue's five trips and $453 below Grand Cayman's.
Two things to price before booking. The budget tier is a floor: at the mid-range tier the same five nights of lodging and food run $545, and Budget Your Trip puts the island's average traveler at $133 a day. And the November dates in the $304 screen sit at the tail of the Caribbean's storm season, which Going links to steep fare swings; on those dates, pay for flexibility or a refundable fare.
Book direct if you want the 24-hour protection, because the rule covers airline-direct tickets and leaves travel agencies outside it. Cozumel's page prints its own cheapest month as January, 20% below the route average, so a trip three months out is past the deepest discount and into the window where the fare usually firms up.
