✈️ Flight Guide: Ontario (ONT) → Silao (BJX)

December in the Bajío region features traditional Las Posadas processions, Christmas markets in Guanajuato City, and festive lighting and concerts in San Miguel de Allende. San Miguel hosts holiday concerts, artisan markets and elaborate nativity displays that attract international visitors during December. León and Guanajuato City offer local holiday parades, seasonal foods and family-friendly events; book transfers early to align with event schedules. Many hotels and restaurants put on special Christmas Eve (Nochebuena) and New Year’s Eve dinners, so reserve in advance. CTA: Plan your December trip around these events and book flights and local transport early to secure the best experience.

For December travel from ONT to BJX, the best fares typically appear when booking 4–8 weeks in advance. Fly on Tuesdays or Wednesdays and avoid the busiest travel windows around December 20–27 to reduce costs and airport congestion. If your schedule is flexible, target early December or the first week of December for the lowest holiday prices. CTA: Start price-watching now and lock in fares when you see a drop — December seats sell out quickly for holiday markets and New Year festivities.

Nonstop flights are faster and more convenient for December holiday travelers, cutting connection risk during busy travel windows. However, nonstop flights may cost more and operate seasonally; connecting flights via Mexico City (MEX) or Guadalajara (GDL) often offer more schedule options and lower fares. If minimizing travel time is your priority — especially for short holiday trips to León or San Miguel de Allende — choose a nonstop when available. If saving money and maximizing departure options is the goal, consider a one-stop itinerary but build in longer layovers to avoid missed connections due to holiday delays. CTA: Compare nonstop and connecting fares now to decide which best fits your December schedule and budget.

Volaris: Often offers low fares and seasonal nonstop services ONT→BJX with a basic economy model; baggage fees apply for carry-on and checked luggage on the cheapest fare classes. Best for budget-minded travelers who pre-pay for extras. VivaAerobus: Another low-cost option with competitive December pricing and frequent promotions; watch for limited seat and bag allowances and consider included bundles for more value. Aeroméxico: Typically provides one-stop connections via MEX; higher base fare but includes greater schedule flexibility and more generous customer service options. Legacy US carriers (United, American): May offer connecting itineraries via U.S. hubs; useful if you have frequent-flyer status or prefer consolidated ticketing. CTA: Compare total trip cost (fare + bags + seat selection) before booking to find the best December carrier for your needs.

Pack layers for December travel to the high-altitude Guanajuato region — warm jackets for evenings and light layers for sunny afternoons. Allow extra time at Ontario International Airport (ONT) for holiday security and traffic, and confirm December return flight times as airlines may add or modify schedules for the season. Book ground transfers from BJX in advance, especially for travel to San Miguel de Allende and Guanajuato City, and verify opening hours of hotels and restaurants on Christmas and New Year’s holidays. Consider travel insurance that covers weather or schedule disruptions common in winter travel. CTA: Prepare now — reserve airport parking, book shuttle transfers, and confirm accommodation to lock in December availability and avoid last-minute price spikes.
