Volaris faces cost pressure from proposed 10% airspace fee hike

A legislative initiative under debate in Mexico's Congress proposes a 10% increase in the fee airlines pay for using Mexican airspace. The measure is part of modifications to the Federal Rights Law within the 2027 Economic Package. Ultra-low-cost carriers such as Volaris would see a sharper impact because their business models rely on low fares, according to Sebastián Martínez, stock analyst at Valmex Casa de Bolsa.

Airspace charges are determined by aircraft wingspan or classification, kilometers flown, and operation type. Independent aviation specialist Fabricio Cojuc explained that these fees typically represent a single-digit percentage of commercial airline operating expenses. However, the hike arrives as carriers handle higher financial costs and softer demand in select markets. Because low-cost carriers serve price-sensitive customers, analysts note it will be difficult to pass the full increase onto passenger ticket prices.

Domestic operators carry the heaviest burden due to their flight volume. According to the Federal Civil Aviation Agency (AFAC), Volaris and Viva together operated 248,919 flights between January and August. By comparison, seven foreign ultra-low-cost carriers operating in Mexico logged 9,354 flights in the same period.

The fee proposal coincides with a planned 75% budget cut for Servicios a la Navegación en el Espacio Aéreo Mexicano (Seneam). The navigation agency would receive 926 million Mexican pesos in 2027 while managing more than 1 million annual operations across over 5.5 million square kilometers. Although authorities justify the fee increase to fund technical operations, independent aviation analyst Carlos Torres noted that the collected revenues are not legally earmarked for Seneam's exclusive use.
