Fare data
Fare brackets shown on route pages come from the Travelpayouts Data API. Every Sunday at 03:00 UTC, an automated job refreshes the per-route minimum-price cache for the corridors covered by FlightsMX. Each cache entry is a point-in-time minimum: the lowest one-way fare available for the cheapest cabin on the most recently sold inventory, expressed in MXN and USD-converted from the original offer when applicable.
We present brackets, not exact prices, because: (a) inventory rolls over hourly, (b) different distribution channels see different prices, and (c) the MXN/USD conversion depends on the exchange rate at fetch time. The brackets shown ("from $X MXN" / "typical $X–Y MXN") reflect the trailing four-week minimum on each route. If a route has fewer than three observations in that period, we mark the bracket as "limited data" rather than show a misleadingly narrow range.
Schedule and route data
Direct/connecting route claims, frequencies, and aircraft-type information come from three sources, in priority order:
- Official airline route maps and IR filings — Aeromexico, Volaris, Viva Aerobus, Iberia, Air France-KLM, Lufthansa, American Airlines, Delta, United, Southwest, Avianca, LATAM, Copa, Air Canada, and other carriers with Mexico routes.
- National regulators — AFAC (Agencia Federal de Aviación Civil), SICT (Secretaría de Infraestructura, Comunicaciones y Transportes).
- Industry trade press — IATA, CANAERO, ch-aviation, route-launch announcements.
When the three sources disagree, we lead with the regulator and note the airline's claim as "announced, pending regulatory approval".
Paisano and CBP data
Paisano-VFR information (baggage, CBP I-94, B1/B2 procedure) is cited from three primary sources: SECTUR Programa Paisano, US Customs and Border Protection (cbp.gov), and INM (Instituto Nacional de Migración). For TSA rules on US-bound flights, we cite tsa.gov directly.
Visa and consular data
Visa requirements and fees come from destination-country embassy or consulate websites (primary), IATA Timatic database (cross-check via airline check-in interfaces), and recent (under 12 months) authoritative reporting on policy changes. We re-verify visa data on a quarterly cadence for high-volume routes and on a six-monthly cadence for the long tail. Every visa claim carries a "verified on" date in the article body.
Currency conventions
MXN is the base currency, with USD shown in parentheses where useful. No ambiguous "$" — always explicit "MXN" or "USD". Conversions use the Banxico FIX rate at the fare-fetch timestamp. We do not embed live currency widgets that change after page load — the rate shown is the rate at fetch time, which preserves consistency between the quoted price and its USD conversion.
Update cadence
- Weekly — Travelpayouts fare refresh (Sundays 03:00 UTC).
- Monthly — Editorial freshness sweep on pillar articles. Price-change deltas >15% from the prior month trigger a re-verify and an updated "Last verified" stamp.
- Quarterly — Visa and consular data re-verification on high-volume routes.
- Bi-annually — Long-tail visa data and minor-airline schedule re-verification.
"Last verified" stamp — what it means
The "Last verified" date on each article reflects the date the data sources behind that specific page were last cross-checked. We do not bump the date for cosmetic edits, internal-link additions, or unrelated changes — only when an editor has re-confirmed at least the fare bracket and one external policy claim. This makes the stamp a meaningful freshness signal rather than a vanity field.
Corrections policy
Material errors get a public correction note at the top of the affected article, dated and signed by the editorial team. We respond to email correction requests sent to [email protected] within 48 hours. Minor typos are fixed silently; substantive corrections (wrong visa fee, wrong baggage allowance, wrong fare range by >20%) get a dated note that remains on the page indefinitely.
Affiliate model and disclosures
FlightsMX earns a small commission when readers book through Aviasales, Hotellook, Skyscanner, Trip.com, Booking.com, AirHelp, and similar partner links. The price you pay is identical with or without the affiliate link. We do not accept paid placement, sponsored airline rankings, or "advertorial" content. See our affiliate disclosure for the full list of partners.
What this methodology does NOT cover
We do not produce live booking quotes — book directly through the linked partner to see the current price and inventory. We do not offer visa-processing services. We do not sell Camino packages — those are the role of licensed operators.
