Time difference against Mexico City. In July, San Juan runs 2 h ahead of the Mexican capital (UTC−4 versus UTC−6). In January the airport operates on UTC−4, so the gap is not constant across the year: daylight saving shifts it. This is the calculation that decides whether a pre-booked ground connection still works.
Coordinates, and why we publish them. 18.439399, -66.002133 is the position from which every great-circle distance on this site is computed, including the ones that set the EU261 compensation band. It is not the distance the aircraft flies — that follows airways and diversions — but the geodesic measure the regulations use. Publishing it lets anyone recompute the figures on these pages.
Airlines at SJU
2 catalogued airlines operate routes to or from SJU: 2 full-service and 0 low-cost, with checked allowance from 23 to 25 kg. Alliances present: SkyTeam. They cover 2 catalogued routes and 12 weekly departures. The table below lists each operator with its type, alliance and checked allowance.
Carriers in our catalogue operating routes to or from this airport, with type, alliance and economy baggage allowance:
| Airline | Type | Alliance | Economy baggage |
|---|---|---|---|
| Aeromexico (AM) | full-service | SkyTeam | 25 kg |
| JetBlue (B6) | full-service | no alliance | 23 kg |
2 kg separate the most generous operator from the leanest at SJU. That gap is what reorders prices once the bag is in: a cheaper base fare on a carrier with no included baggage can land above a full-service one the moment you check a single piece. Compare the total, not the headline figure.
Alliances present at SJU: SkyTeam. It matters for two concrete things: where miles credit, and what happens when something breaks. Within one alliance, rebooking onto another member is usually provided for; between carriers with no agreement it does not exist and depends on goodwill at the desk. If you buy two legs on operators from different alliances, treat them as two separate trips.

Connection tips
SJU concentrates 12 catalogued weekly departures across 2 airlines, in the America/Puerto_Rico zone. That density is what decides how much slack to leave on a connection: the more of its own services the airline runs here, the more same-day rebooking options exist.
Aeropuerto Internacional Luis Muñoz Marín runs on the America/Puerto_Rico time zone; factor the offset from your origin city when planning connections and transfers. The busiest route at SJU is CUN-SJU (~7 flights a week). Book 4–8 weeks ahead for the busiest routes to/from San Juan; fares climb in December, Holy Week and summer. Each route guide above shows month-by-month seasonality and the lowest peso fare. 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.
The cheap connection that loses the checked bag. Two separate tickets are not one itinerary: there is no interline agreement, the bag is not checked through to the final destination, and if the first flight lands late the second airline owes you nothing — it sold a different flight. The apparent saving evaporates the moment you buy a same-day replacement. On a single ticket, rebooking and the bag transfer are the carrier’s problem, not yours.
