Return flights are similar in duration; some itineraries via MEX on Aeromexico can be on the shorter end." }, "q1": { "question": "Are there any direct flights from Cancún to San Diego?", "answer": "There are no nonstop flights from Cancún to San Diego. The most common one‑stop routing connects through Houston (IAH) on United, with a total travel time around 7½ to 8 hours including a layover. United also offers connections via San Francisco, Los Angeles, and Denver, while American connects through Dallas/Fort Worth and Southwest through Houston Hobby.", "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).

Mexican citizens can travel to the U.S. without a visa only if they hold a valid Border Crossing Card or are otherwise exempt. Other nationals should check U.S. entry requirements, as many require an ESTA or visa.

Public transit via bus route 992 connects directly to downtown in about 15–25 minutes for just $2.50, while the airport’s free shuttle to the rental car center makes picking up a vehicle easy. Taxis offer flat-rate fares to downtown and nearby areas, but ride share is often faster and cheaper.

It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.

Booking about 45 days out can also yield a similarly low fare of $617, but prices rise sharply closer to the travel date, reaching $852 on the day of departure.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.
