Geneva, 2 September 2025: Wizz Air Holdings Plc ("Wizz Air"), one of the most sustainable and fastest-growing European airlines, today reports accelerated traffic growth and record-low emissions intensity for August 2025.
Wizz Air carried 6.91 million passengers during the month of August, an 11.4% increase year on year. Seat capacity increased 12.1% year on year, with a resilient load factor of 94.8%, down only -0.60 ppt on last year's load factor of 95.4%, demonstrating continued strong demand.
During the month:
- Wizz Air continues to be one of the lowest emission airlines in August, reporting a further decline in CO2 emissions per RPK to 49.6 grams, down -2.5% year on year. This is only the second time in the last seven years that Wizz Air has delivered a number below 50 grams per RPK (Feb. 2023) and highlights the growing beneficial impact of its A321 neo deliveries, enhancing long-term cost discipline and sustainability leadership.
- While the last originating service from its to-be-closed Abu Dhabi base flew on August 31st, Wizz Air continues to rebuild its Tel Aviv station following the Summer suspension, with a full service of 24 routes to be deployed by mid-September. This underscores flexibility and resilience.
- On August 19th, Wizz Air announced a strategic distribution partnership with Travelfusion, the world's largest flight content aggregator, which will help WIZZ better reach the 45% of travellers in Europe who still prefer to book through a retail channel (source: GBTA Business Travel Index Outlook report 2024), positioning Wizz Air for incremental revenue growth and expanded market reach.
