Mexico travel alert: cartel violence prompts shelter-in-place advisories in tourist hubs

After cartel boss El Mencho was killed in Jalisco, violence led to roadblocks and arson, prompting US and UK travel advisories to shelter indoors in areas like Puerto Vallarta and Guadalajara. Some international flights to Puerto Vallarta and Guadalajara were disrupted or rescheduled, though airports remain open and others (Baja California, Quintana Roo, Oaxaca) reported normal operations as authorities coordinate with security forces. Airlines have waived change fees in some cases, and travelers should stay alert and follow local guidance, as the situation can evolve.
