Volaris Reports November 2024 TrafficResults:Load Factor of 87%

Mexico City, Mexico, December 5, 2024 – Controladora Vuela Compañía de Aviación, S.A.B. de C.V. (NYSE: VLRS and BMV: VOLAR) (“Volaris” or “the Company”), the ultra-low-cost carrier (ULCC) serving Mexico, the United States, Central and South America, reports its November 2024 preliminary traffic results.

In November, Volaris' ASM capacity decreased by 3.7% year-over-year due to the Pratt & Whitney engine inspections offset by fewer aircraft groundings following the return of the initial batch of inspected engines. Volaris transported 2.6 million passengers during the month with a load factor of 86.8%, a 3.0 pp decrease from last year. RPMs for the month declined by 6.9%, with Mexican domestic RPMs down 10.5%, while international RPMs were effectively flat. When comparing year-over-year RPMs and load factor results it is useful to note that our 2023 figures were impacted by the accelerating engine inspections. Last year, we had to reduce operations as engines temporarily left our fleet; today, we are gradually adding capacity as engines and aircraft return.

EnriqueBeltranena, Volaris’ President and CEO, said: “Demand remains solid across the Volaris network, particularly as the domestic market continues to be resilient. Heading into the winter season, we continue strategically investing in the transborder market. In November, we added transborder capacity in preparation for the December high season, which is ramping up. We see this ramping well into the peak holiday season and will continue to manage low-season demand elasticity through capacity adjustments when necessary.” **Mr. Beltranena added: “**We are pleased with our strong operating figures year-to-date despite the headwinds, such as the GTF engine inspections.”

It cannot be inferred that any period’s performance or its comparison year-over-year will indicate a similar performancein the future. Figures are rounded for convenience purposes.
