Puerto Vallarta, Mexico – Flights to several Mexican resort cities were disrupted Sunday as reports emerged of clashes in Jalisco state following a military operation targeting Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Cartel de Jalisco Nueva Generación (CJNG). US and Canadian airlines swiftly canceled services to popular destinations including Puerto Vallarta and Guadalajara, citing safety concerns for passengers and crew. The situation underscores the ongoing challenges Mexico faces in combating powerful drug cartels and the ripple effects these conflicts have on international travel and security.
The cancellations began Sunday morning, with United Airlines leading the way by suspending all flights to Puerto Vallarta (PVR) and Guadalajara (GDL). Southwest Airlines followed suit, canceling all flights to and from Puerto Vallarta. American Airlines halted service to Puerto Vallarta, Guadalajara, and Mazatlán, while Air Canada temporarily suspended operations in Puerto Vallarta. The swift response from these airlines highlights the sensitivity surrounding travel to regions experiencing cartel-related violence and the priority placed on passenger safety. Several airlines too issued travel waivers, allowing affected passengers to rebook flights without incurring change fees.
Operation Targeting ‘El Mencho’ Triggers Violence
The disruption to air travel followed a reported military operation in Tapalpa, Jalisco, aimed at capturing or eliminating El Mencho. While initial reports indicated El Mencho was killed during the operation, confirmation remains complex. The Mexican government has not officially confirmed his death as of this writing, but the operation sparked a wave of violence across the state. According to reports, cartel members responded to the military action with roadblocks, arson, and clashes with security forces. The US Department of State issued shelter-in-place advisories for multiple states in Mexico, including Jalisco, urging US citizens to exercise extreme caution.
The Cartel de Jalisco Nueva Generación, under El Mencho’s leadership, has grown into one of Mexico’s most powerful and violent criminal organizations. The CJNG has expanded its operations beyond drug trafficking, engaging in activities such as extortion, kidnapping, and human trafficking. US authorities have identified the cartel as a major supplier of fentanyl to the United States, contributing to the ongoing opioid crisis. The US Drug Enforcement Administration (DEA) has offered a $15 million reward for information leading to El Mencho’s arrest. DEA Most Wanted
Airline Responses and Passenger Impact
The immediate impact of the flight cancellations was felt by thousands of travelers with plans to visit or depart from affected Mexican cities. United Airlines stated its decision was made “to ensure the safety of our customers and employees,” while Southwest Airlines emphasized its commitment to prioritizing safety. American Airlines similarly cited safety and security concerns as the reason for halting flights. The airlines’ swift action reflects a heightened awareness of the risks associated with operating in regions experiencing cartel violence.
Passengers stranded at airports in Guadalajara and Puerto Vallarta faced significant disruptions and uncertainty. Reports from Guadalajara International Airport described scenes of panic as travelers rushed to rebook flights or seek alternative transportation. The situation was further complicated by limited transportation options and concerns about safety outside the airport. Airlines are working to accommodate affected passengers, but the extent of the disruption is expected to continue in the coming days as the situation in Jalisco remains volatile.
US-Mexico Cooperation and Regional Security
The military operation targeting El Mencho reportedly involved bilateral coordination and cooperation between Mexican and US authorities. The Mexican Defense Department stated that US intelligence contributed to the operation, highlighting the ongoing collaboration between the two countries in combating drug trafficking and organized crime. This cooperation is crucial, given the transnational nature of the drug trade and the significant impact it has on both Mexico and the United States. US Deputy Secretary of State Christopher Landau stated on X (formerly Twitter) that El Mencho’s reported death was “a great development for Mexico, the US, Latin America, and the world.”
I’ve just been informed that Mexican security forces have killed ‘El Mencho,’ one of the bloodiest and most ruthless drug kingpins. What we have is a great development for Mexico, the US, Latin America, and the world. The fine guys are stronger than the bad guys.

Although, experts caution that the removal of a cartel leader does not necessarily equate to the dismantling of the organization. Cartels often have deep-rooted structures and multiple layers of leadership, allowing them to adapt and continue operating even after the loss of key figures. The CJNG, in particular, has demonstrated a remarkable ability to withstand pressure from law enforcement and maintain its influence in key regions of Mexico.
The Rise of El Mencho and the CJNG
Nemesio Oseguera Cervantes, known as “El Mencho,” rose to prominence following the arrest of Joaquín “El Chapo” Guzmán, the former leader of the Sinaloa Cartel. While El Chapo’s Sinaloa Cartel once dominated the Mexican drug trade, the CJNG has emerged as a formidable rival, challenging its dominance and expanding its operations across Mexico and internationally. Over the past 15 years, the CJNG has evolved from a regional criminal group into a global trafficking organization with a significant presence in the United States, Europe, and Asia.
The cartel’s success is attributed to its aggressive tactics, its willingness to use violence, and its ability to adapt to changing market conditions. The CJNG has also been adept at utilizing technology and social media to promote its brand and intimidate rivals. Its control over key transportation routes and its ability to corrupt local officials have further solidified its power. The cartel’s primary source of income remains drug trafficking, particularly fentanyl, but it has also diversified into other criminal activities, including extortion, kidnapping, and illegal mining.
Looking Ahead: Continued Uncertainty and Travel Advisories
The situation in Jalisco remains fluid and unpredictable. While Mexican authorities continue to assess the aftermath of the military operation, the potential for further violence remains high. Travelers planning to visit Mexico, particularly the states of Jalisco, Guanajuato, and Michoacán, are advised to exercise extreme caution and monitor travel advisories issued by their respective governments.

Airlines are expected to continue monitoring the situation closely and adjust their flight schedules accordingly. Passengers with upcoming travel plans to affected areas should check with their airlines for the latest updates and potential cancellations. The long-term impact of this event on the region’s security and stability remains to be seen, but it underscores the ongoing challenges Mexico faces in its fight against organized crime and the need for continued international cooperation.
The next official update is expected from the Mexican Defense Department within the next 24-48 hours regarding the confirmation of El Mencho’s death and the extent of the ongoing security operation.
