Base of Aeromexico, Volaris. An airline basing here means aircraft and crews overnighting at the airport: more of its own services to rebook a disrupted passenger onto, and more early departures. The flip side is that at an airport dominated by one carrier the competitive pressure on fares is weaker than where several compete.

What each code is for. The IATA code (BJX) is what the bag tag and the ticket use; the ICAO code (MMLO) is what flight plans, NOTAMs and flight trackers use. To follow the inbound aircraft that will become your flight, ICAO is the one that returns reliable results. And if BJX is not printed on your bag tag, the bag was not checked through to here — worth catching at the counter.

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 from BJX 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.

25 kg separate the most generous operator from the leanest at BJX. 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.

Why some rows have no fare. Of the 5 routes listed, 1 returned a price on the collector’s last pass and the rest show a dash. A dash means the automated query got no result for that pair — not that the route is suspended or expensive. For those pairs the reference price comes from the live search, which queries current inventory.

Connection tips

BJX concentrates 36 catalogued weekly departures across 3 airlines, in the America/Mexico_City 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 del Bajío runs on the America/Mexico_City time zone; factor the offset from your origin city when planning connections and transfers. The busiest route at BJX is BJX-DFW (~10 flights a week). The lowest fare detected at this airport is $3,876 MXN on the BJX-ATL route. Book 4–8 weeks ahead for the busiest routes to/from León / Silao; 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.

Great-circle distance is not the transfer. The figures in the table are geodesic, computed from each airport’s coordinates; the real journey depends on whether road, rail or a domestic flight exists, and on what they cost. An airport 300 km away can be more accessible than one at 120 km if the first has a direct motorway and the second does not. Use them to rule out, not to plan.
