The return leg is shorter at about 6 hours 1 minute, a difference of 44 minutes due to prevailing winds.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": [ "flight_schedule" ] }, "q1": { "question": "Are there any direct flights from Cancún to Seattle?", "answer": "Delta and Alaska Airlines both fly nonstop from Cancún to Seattle, with flights operating daily. Delta runs about 38 weekly flights with afternoon departures, while Alaska offers around 21 weekly flights also departing in the afternoon. Typical fares run around $794 on Delta and $1,158 on Alaska.", "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports.

Taxis and rideshares pick up on the third floor of the parking garage, with metered taxis available on the north and south curbs.

June and July are also pricey, averaging $470–$479, and the route's low season spans September, January, October, and February.", "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.

Prices rise notably if you book more than 8-10 weeks ahead, climbing to $460 at 175 days out, and they also tick up when booking within the final two weeks. For summer or holiday periods, demand is higher, so you'll generally want to book a bit earlier than the usual window to secure the best price.", "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window.

No nonstop red-eyes operate on this route.", "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.", "toolsUsed": [ "redeye_flights" ] }, "q7": { "question": "Which airlines usually operate this route from Cancún to Seattle?", "answer": "Delta and Alaska Airlines operate non‑stop from Cancún to Seattle, with Delta flying about 38 flights a week and Alaska around 21.

Paine Field in Everett is a smaller alternative about 25 miles north, used by Alaska Airlines for limited West Coast routes and offering a quieter experience, but it lacks international service." }, "q13": { "question": "How do I get to Cancún Intl Airport from the city center?", "answer": "From downtown Cancún, the fastest and most popular way to reach the airport is by pre-booked private shuttle, which offers door-to-door service in about 25 minutes; shared shuttle vans are a cheaper alternative with slightly longer travel time due to multiple stops. Taxis are widely available and provide a direct ride, but they are generally more expensive than shared shuttles. Public buses (ADO) serve the airport from the downtown bus station and are the most economical choice, though they run on fixed schedules and can be slower. Ride-share apps like Uber are not permitted to pick up at the airport, but you can use them to reach the airport from the city center, typically at a cost between a shared shuttle and a taxi.", "toolsUsed": [], "references": [ { "url": "https://airportcun.com", "title": "Cancun Airport Official Information | CUN | Arrivals, Departures and Transfers", "time_published": "2026-01-01T00:00:00Z" }, { "url": "https://www.airport-cun.com/lounges.php", "title": "Lounge Cancun Airport (CUN)", "time_published": "2026-01-01T00:00:00Z" }, { "url": "https://www.airport-cun.com/terminal-3.php", "title": "Cancun Airport Terminal 3", "time_published": "2026-01-01T00:00:00Z" }, { "url": "https://airportcun.com/private-transportation", "title": "Cancun Airport Private Transfers | Cancun International Airport (CUN)", "time_published": "2024-04-30T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/Canc%C3%BAn_International_Airport", "title": "Cancún International Airport", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-07-15T22:11:41Z" } ] }, "q14": { "question": "Are there hotels or sleeping facilities at Seattle airport?", "answer": "Seattle-Tacoma International Airport (SEA) does not have on-site hotels, capsule hotels, or sleeping pods inside the terminal.
