Mexico Probes Viva, Volaris Under Grupo Más

The proposed creation of Grupo Más Vuelos, a holding company that would group low-cost carriers Viva Aerobus and Volaris under a single parent entity, has prompted heightened regulatory scrutiny amid concerns about its potential impact on competition and pricing dynamics in Mexico’s aviation market.

Under the plan, both airlines would retain separate operations and brands but share common ownership through the new holding structure. Mexico’s National Antimonopoly Commission (CNA) is reviewing the transaction to determine whether it constitutes a concentration that could substantially lessen competition, particularly on overlapping routes or in markets where the carriers hold significant shares.

Rogelio Rodríguez, an aviation analyst, said regulators should closely examine post-transaction pricing behavior. He warned that the airlines’ combined market position could allow them to maintain the perception of low fares while raising average ticket prices. “The key question is how fares will behave once the holding is in place,” Rodríguez said in an interview with El Norte.

He described a potential scenario in which a limited number of seats are sold at promotional rates, while the majority are priced at higher levels comparable to full-service carriers. On aircraft with roughly 150 passengers, he said, the structure of fare buckets could influence average pricing outcomes. Such dynamics could become more pronounced on routes with limited competition or high concentration.

Rodríguez also pointed to cost differentials between low-cost carriers and full-service airlines. He noted that labor expenses, including pilot compensation, are materially lower at low-cost operators, reflecting differences in collective bargaining agreements and operational models. “Their cost base is structurally lower, which should translate into sustained fare differentiation,” he said.

Beyond pricing, Rodríguez suggested the holding could influence investment and capacity growth strategies. Viva is owned by Grupo IAMSA, a major intercity bus operator with extensive national coverage. He argued that slower fleet expansion in aviation could indirectly benefit ground transportation, although he acknowledged that such outcomes would depend on broader market conditions.

Viva and Volaris have said the holding aims to strengthen their financial position, enhance capital access and improve cost efficiencies while preserving operational independence. The airlines maintain that the structure would expand access to low-cost air travel rather than restrict competition.

Juan Carlos Machorro, head of the transactional practice, Santamarina y Steta, said the transaction clearly qualifies as a concentration under Mexico’s competition framework regulation.  “From an antitrust perspective, any operation that consolidates control between significant market participants requires authorization,” Machorro said. He added that the CNA’s first step will be to define the relevant market—whether broadly as domestic aviation or more narrowly as the low-cost segment.

Market definition could prove decisive. Viva and Volaris together account for more than 40% of Mexico’s total aviation market, roughly double Aeroméxico’s share. If regulators define the relevant market as low-cost carriers, the combined entity would represent the entirety of that segment following Interjet’s exit.

The transaction is also expected to face review in the United States due to cross-border operations and potential competitive implications on international routes.

Jonathan Félix, analyst, Verum, said route overlap between Viva and Volaris is more limited than headline market share figures suggest. A significant portion of each carrier’s network operates without direct competition, he noted. However, he identified high-traffic corridors—such as routes serving Mexico City, Guadalajara, Tijuana and Cancun—as areas where competitive effects could be more visible over time.
