Volaris and VivaAerobus often offer the lowest fares from Del Bajío International Airport (BJX) to U.S. gateway hubs like LAX or PHX, but their low-cost model means baggage and seat selection incur extra fees. Aeroméxico provides stronger interline connections and may offer smoother single-ticket transfers through Mexico City (MEX) or U.S. hubs. For the U.S. leg to Reno-Tahoe International Airport (RNO), Alaska Airlines, United, American, and Southwest offer frequent schedules—Alaska and Southwest have strong West Coast networks into RNO. When booking in November, compare total trip cost including baggage fees, preferred connection times, and winter-travel flexibility.
