The budget airline also announced that it plans to cut its CO2 emissions by one third for every passenger over the next decade.
In May, the carrier emitted 319,760 tonnes of CO2, or 56.5g per passenger per kilometre, down 4.4% compared to last year. It carried 3.47mln passengers and flew 5,656km.
Wizz Air said the reason has the smallest footprint per passenger is because its fleet of Airbus A320, A321CEO and A321NEO aircraft are fuel efficient and have an average age of 4.7 years – one of the youngest in the industry.
“We have set ambitious goals for ourselves to further reduce the impact on the environment by deploying the latest state-of-the-art technology and further reducing CO2 emissions per passenger by a third by 2030,” said chief executive József Váradi.
“We have the best tools to achieve this - the A321NEO aircraft with Wizz Air's seat configuration of 239 passenger seats and Pratt and Whitney's Geared Turbofan engines bring the cleanest and most environmentally-friendly technology that currently exists in the world."
