Flights Ciudad de México to Denver (MEX-DEN): airlines, frequency

Flights Ciudad de México → Denver: airlines, fares, timing

The MEX–DEN route appears in our catalogue with 14 weekly departures (~2.0 per day) across 2 airlines, 3.5 h of block time and 2,333 km great-circle between Ciudad de México and Denver. Demand score: 6/10, classified as the Mexico-US paisano corridor.

Mexico City to Denver links the capital with Colorado, with around 14 flights a week. The route carries business travellers, families visiting relatives, and tourists drawn by the Rocky Mountains. Block time is around three and a half hours, a direct sector.

At ~2.0 departures a day there is daily service but little cushion: if the flight cancels, the same airline’s next option is usually the following day. Leave slack on any onward connection and avoid buying the last departure of the day when something is booked after it.

How to read these figures. Weekly departures are an aggregate estimate from the published schedules of every catalogued carrier on the pair, one-way; the flight time is block time — gate to gate, taxi included — not airborne time. Neither is a schedule guarantee: carriers cut frequencies in low season without notice.

Airlines operating this route

2 airlines operate MEX–DEN: Aeromexico, United Airlines. 2 are full-service and 0 low-cost; included checked allowance ranges from 23 to 25 kg depending on the operator. Between them they run 14 weekly departures over 3.5 h of block time; alliances present: SkyTeam, Star Alliance.

Two carriers fly MEX-DEN: Aeroméxico and United Airlines, both full-service with checked baggage and meals included. United has one of its main hubs in Denver, offering wide onward connections across the western US. Both fly direct, so the choice is in schedule and price.

The honest comparison already has the bag in it. Between the most generous operator (25 kg) and the leanest (23 kg) there are 2 kg of difference in the base fare. On a 3.5 h sector onboard comfort matters little; total cost is decided by baggage and, if you travel with family, by seating you together.

MXN fares — what to expect

The cached minimum for MEX-DEN is $7,837 MXN one-way. By month with data, the floor runs from $4,473 MXN in Jul 2026 to $4,473 MXN in Jul 2026: 0% between the cheapest and priciest months observed. On the collector’s last pass, 34 of 109 catalogued corridors returned a price.

MEX-DEN follows the family and ski-season calendar — December and winter push prices up, and the summer is a peak again. For those dates, booking two to three months ahead is sensible. Outside the peaks, five to seven weeks usually covers a reasonable fare in MXN.

Buying window: a general market rule of thumb. At demand 6/10 and 14 weekly departures the usual reference is 4 to 8 weeks ahead on ordinary dates and 8 to 12 weeks for December, Holy Week and summer. That is a general Mexican-market rule of thumb, not a measurement of MEX-DEN: our series records observed prices, not the lead time at which each ticket was bought. What the data does support is that the lower the frequency, the sooner cheap inventory runs out.

About Denver

Denver (DEN) appears in 1 route in our catalogue from 1 Mexican airport, totalling 14 weekly departures. The lowest fare detected into DEN departs MEX at $7,837 MXN. Denver International Airport (DEN, ICAO KDEN) lies 2,333 km from Ciudad de México and runs on America/Denver.

Denver is the capital of Colorado, a city at the foot of the Rocky Mountains known for its altitude, its mountain climate and its role as the gateway to the state’s ski resorts. For Mexican travellers it is a business and family-visit destination, and also a starting point for the western US.

Destination record. Denver — Rocky Mountain paisano corridor. Mexican community in Westwood and Aurora.

DEN as a hub. Denver is a base for United Airlines, and that changes what to expect on the ground: more of the airline’s own frequencies to be rebooked onto, more onward destinations from the same terminal and, where the home carrier dominates, less competitive pressure on fares. It matters most when DEN is your connecting point rather than your final destination.

Currency and paperwork at destination. Spending in Denver runs in USD, while the fare is compared in pesos. For a Mexican passport our record lists: B1/B2 required. That field is a starting reference; the real requirement depends on the purpose of travel and is set by the destination’s immigration authority, not the airline.

How the MEX-DEN fare has moved

Across 5 weekly readings between 2026-W23 and 2026-W29 of 2026, the detected minimum for MEX-DEN moved between $4,521 MXN and $6,610 MXN, a 46% range. The cheapest reading fell in week 2026-W23. The latest reading sits 5% above the one before it.

What a 46% range means. Dispersion like that between readings taken in different weeks says the price of MEX-DEN depends far more on when you look and which dates you search than on the airline. It is not a trend: these are point samples of the available floor, and a low floor usually corresponds to awkward dates — pre-dawn departures, midweek, off-season — rather than to a general market drop.

Method and limits of this series. These are 5 observations, one per collector pass, taken between 2026-W23 and 2026-W29 on the same pair and in the same currency (MXN). It is not a price index: it does not control for departure date, booking lead time or fare class, and a missing week means the query returned nothing, not that no flights existed. At that N it is good for placing today’s quote inside a known range, and for nothing else.

Passenger rights on the MEX–DEN route

25% of the ticket price is the minimum Art. 47 Bis of the Ley de Aviación Civil requires on the MEX → DEN leg, which departs Mexico, for a delay over 4 h attributable to the airline. On the return from the United States there is no federal delay compensation.

What does apply on departure from Mexico. Mexico’s Ley de Aviación Civil (Art. 47 Bis), enforced by AFAC and PROFECO, covers flights taking off from Mexican territory regardless of the airline’s nationality: a delay over 4 hours attributable to the carrier entitles you to at least 25% of the ticket price, and from the first hour the airline owes assistance that escalates with duration. Keep the boarding pass and the purchase receipt — a claim stands on those two documents.

What US DOT does not cover. The United States has no federal delay compensation: the Department of Transportation regulates refunds — your money back when the airline cancels or significantly changes the flight and you decline the alternative — but it does not require a payout for the hours you lost, the way EU261 does. The single federal exception is involuntary denied boarding from oversales, priced under 14 CFR Part 250; that is a different mechanism from delay and is not triggered by a late departure.

Documents to sort out before buying

Verified 2026-05-18: with a Mexican passport, Estados Unidos requires Visa B1/B2 obligatoria, at a cost of $185 USD no reembolsable and a maximum stay of Decidido en POE; típicamente 6 meses. Confirm the current amount before paying. Buying the ticket before the document exists is the expensive mistake on this route.

Check the current amount before paying. The consular fee and stay limit above are the ones in our immigration file, last verified on 2026-05-18. Consulates revise those amounts without notice and publish no change calendar, so confirm the current figure at the official source on the day you pay. A receipt issued at the old rate is neither refunded nor credited — it is simply paid again.

The right order: document first, ticket second. A cheap fare does not survive a pending immigration formality. The airline will not refund a non-refundable ticket because your visa was denied or delayed, and the change fee usually exceeds the saving you were chasing. Consular appointment waits run 30–180 days depending on the post, and buying the ticket first does not speed them up. Buy once the document is issued, or buy a changeable fare and accept that the premium is the price of the risk.
