Flights Ciudad de México to Quito (MEX-UIO): airlines, frequency

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

The MEX–UIO route appears in our catalogue with 7 weekly departures (~1.0 per day) across 2 airlines, 4.8 h of block time and 3,136 km great-circle between Ciudad de México and Quito. Demand score: 6/10, classified as the Latin American regional corridor.

Mexico City to Quito links the Mexican capital with the capital of Ecuador, with around 7 flights a week, one a day. The route carries business travellers, tourists and passengers connecting onward across the rest of the Andean region. Block time is about four and three-quarter hours.

At ~1.0 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–UIO: Aeromexico, Avianca. 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 7 weekly departures over 4.8 h of block time; alliances present: SkyTeam, Star Alliance.

Two carriers fly MEX-UIO: Aeroméxico, full-service with baggage included, and Avianca, with a leaner base-fare product. Both fly direct to Quito, so the decision is between full service and a product to which baggage is added.

The allowance belongs to the fare, not to the passenger. The kilos listed are those of the published base fare. ‘Basic’, ‘light’ and ‘zero’ families on several carriers exclude the checked bag, seat selection and sometimes date changes, even though the flight and the aircraft are identical. The carrier’s AM Paisano (1ra maleta gratis 25kg internacional) programme attaches to specific fare families: buy the cheapest bucket and the benefit does not travel with you. Always compare with the bag already added: on short sectors the ranking of operators usually flips once it is in.

MXN fares — what to expect

There is no live cached fare for MEX-UIO, but 4 historical readings exist between 2026-W20 and 2026-W27: the observed floor in that window was $3,739 MXN and the ceiling $10,144 MXN. Only 34 of 109 corridors returned a price on the last pass.

MEX-UIO fares climb in the summer, December and Holy Week. For those dates, booking one to two months ahead is sensible. Outside the peaks, four to six weeks usually secures a reasonable fare in MXN.

Buying window: a general market rule of thumb. At demand 6/10 and 7 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-UIO: 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.

Two currencies, two budgets. The fare is compared in pesos because that is what leaves your account, but spending at destination runs in USD. A fare quoted in foreign currency and charged in pesos by your bank adds the conversion spread, and choosing to pay in pesos at a foreign terminal (dynamic currency conversion) is almost always worse than letting the bank convert. Budget the flight in MXN and the stay in USD separately.

About Quito

Quito (UIO) appears in 1 route in our catalogue from 1 Mexican airport, totalling 7 weekly departures. Aeropuerto Internacional Mariscal Sucre (UIO, ICAO SEQM) lies 3,136 km from Ciudad de México and runs on America/Guayaquil. The flight from Ciudad de México runs 4.8 h block time per our catalogue.

Quito is the capital of Ecuador, a high-altitude city in the Andes with a historic centre listed as a World Heritage Site. It is also a gateway to the Ecuadorian Andean region. For Mexican travellers it is an urban destination and a regional connecting point.

Destination record. Quito — Ecuadorian capital, UNESCO heritage, equator line. Dollarized.

Currency and paperwork at destination. Spending in Quito runs in USD, while the fare is compared in pesos. For a Mexican passport our record lists: Sin visa Mercosur asociado 90 días. 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.

UIO as a hub. Quito is a base for Avianca, 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 UIO is your connecting point rather than your final destination.

How the MEX-UIO fare has moved

Across 4 weekly readings between 2026-W20 and 2026-W27 of 2026, the detected minimum for MEX-UIO moved between $3,739 MXN and $10,144 MXN, a 171% range. The cheapest reading fell in week 2026-W27. The latest reading sits 55% below the one before it.

What a 171% range means. Dispersion like that between readings taken in different weeks says the price of MEX-UIO 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 4 observations, one per collector pass, taken between 2026-W20 and 2026-W27 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–UIO route

25% of the ticket at minimum for a delay over 4 h attributable to the airline: that is what Art. 47 Bis of the Ley de Aviación Civil sets on the MEX → UIO leg, which departs Mexico. On the return from Ecuador the departure country’s regulator governs.

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.

Documents to sort out before buying

1 requirement is what our destination record lists for Quito (UIO) on a Mexican passport: Sin visa Mercosur asociado 90 días. That is a starting point, not a ruling on your case: requirements change with the purpose of travel, the length of stay and each person’s immigration history.

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. Buy once the document is issued, or buy a changeable fare and accept that the premium is the price of the risk.

Minors and mismatched surnames. When a minor travels with one parent or with third parties, the airline and immigration may ask for the other parent’s authorisation, and the name on the ticket must match the passport letter for letter. A second surname dropped at purchase counts as a name change and many fares charge it as a reissue. Check it on the passenger screen before confirming.
