Travellers reach Puerto Rico from 2 Mexican airport(s) on 2 catalogued routes, operated by Aeromexico, JetBlue. This page gathers every route to the destination, with airlines, weekly frequency and the lowest fare detected. Airfares are quoted in pesos (MXN); on-the-ground spend is in USD.
Routes to Puerto Rico
Our catalogue lists 2 routes to Puerto Rico from 2 Mexican airports, totalling 12 weekly departures across 2 airlines. Distances run 2,202 to 3,475 km, and 1 routes carry a cached fare, and the country appears with 1 airports in the catalogue.
| Route | Airlines | Freq/wk | Fare from | Guide |
|---|---|---|---|---|
| Cancún (CUN) → San Juan (SJU) | AM, B6 | ~7/wk | $7,195 MXN | CUN-SJU |
| Ciudad de México (MEX) → San Juan (SJU) | AM | ~5/wk | — | MEX-SJU |
The corridor that sets the price floor. CUN-SJU is the highest-frequency route to Puerto Rico at ~7 weekly departures, and that is usually why it is cheapest: it has the most seats competing. If your city is not Cancún, compare your direct route against reaching that corridor first by road or domestic flight.
How these routes are counted. They are the pairs with a Mexican origin airport and a destination in Puerto Rico present in our catalogue, one-way; weekly frequency adds up departures from every carrier on the pair. It is not a complete map of connectivity between the two countries: pairs we do not cover editorially, and pairs that exist only with a connection, are out of scope.
Airlines to Puerto Rico
2 airlines cover the Mexico-Puerto Rico routes: 2 full-service and 0 low-cost and allowances from 23 to 25 kg. 0 of them are registered in the destination country, which changes the rights regime that applies on the return leg.
| Airline | Type | Alliance | Economy baggage |
|---|---|---|---|
| Aeromexico (AM) | full-service | SkyTeam | 25 kg |
| JetBlue (B6) | full-service | no alliance | 23 kg |
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.
2 kg of difference between operators. That gap decides which airline is genuinely the cheap one to Puerto Rico: a lower base fare on an operator with no included bag ends up higher the moment you check one. Compare with the bag already in and, travelling as a group, multiply the fee by the number of pieces before deciding.
Visa & currency
0 verified immigration records exist here for Puerto Rico, despite the 2 catalogued routes there, so we publish no specific requirement: check with the embassy before buying. Spending at destination runs in USD and the airfare is compared in pesos.
Visa for a Mexican passport: B1/B2 required (territorio US)
Currency: USD. Budget your destination spend in USD; compare airfares in MXN.
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.
A US layover needs a visa too. The United States has no visa-free international transit: with a Mexican passport you need a B1/B2 or C-1 visa merely to change planes in Houston, Dallas, Miami or Atlanta, even without leaving the terminal. Every US connection forces you through immigration, bag reclaim, customs and re-check. A US-routed itinerary that looks cheaper can therefore be unusable if your visa has expired or is still in process.
When to buy
There is no monthly breakdown for Puerto Rico, but 5 weekly collector readings exist across 1 corridors: the observed floor runs $6,500 MXN to $8,569 MXN. That dispersion measures how much the floor moves between query weeks, not between airlines.
Book 6–10 weeks ahead. Fares climb in December, Holy Week and summer, when demand rises. See month-by-month seasonality in each route guide above. That window is a general Mexican-market rule of thumb, not a measurement of this route: our series records observed prices, not the lead time at which each ticket was bought.
Buying window: a general market rule of thumb. As a general Mexican-market rule of thumb — not a measurement of the routes to Puerto Rico — booking runs 4 to 8 weeks ahead on ordinary dates and 8 to 12 weeks for December, Holy Week and summer. Our series records observed prices, not the lead time at which each ticket was bought, so no figure on this page measures that window.
Why those three peaks and no others. December, Holy Week and summer concentrate family and leisure travel at once, and in those windows the airline no longer needs low fares to fill the aircraft. Outside them the usual pattern rewards midweek departures and avoiding Friday evening and Sunday, the two moments when most people compete for the same seat.
Departure airports for Puerto Rico
2 Mexican airports have a catalogued route to Puerto Rico, across 2 routes and 12 weekly departures between them and 2 airlines involved. The busiest origin is Cancún (CUN) at ~7 weekly departures. Departure distances run 2,202 to 3,475 km. The lowest floor to Puerto Rico departs CUN at $7,195 MXN.
| Departure airport | Routes | Freq/wk | Distance | Fare from |
|---|---|---|---|---|

| Ciudad de México (MEX) | 1 | ~5/sem | ~3,475 km | — |
Departing from another city is a total-cost decision. The fare gap between departure airports for Puerto Rico only pays if it beats the ground transfer, the preceding domestic flight and the hotel night an early departure sometimes forces. Reaching the airport by road also adds a risk the airline does not carry: miss the international flight in traffic and the ticket is not refunded.
The departure airport changes more than the price. It changes which airline is available, and with it the included allowance; it changes frequency, and with it the rebooking room if something breaks; and it changes the realistic departure hour, which on an early flight decides whether you need to sleep near the airport. Read the table by frequency before fare: the origin with the most departures is usually also the one that best absorbs a disruption.
