Wizz Air saw passenger carryings collapse by more than a third in March as the impact of coronavirus on European travel took its toll.
The Hungarian budget airline was forced to cut capacity by 34% after traveller numbers fell by more than 35% year-on-year to 1.7 million.
The airline has since cancelled many of its flights including almost all routes from Luton airport until May 1.
Wizz Air said: “As a result of the Covid-19 pandemic and subsequent travel restrictions introduced by governments across Europe, Wizz Air had to reduce its capacity by 34% year-on-year for the month of March.
“Wizz Air operated rescue flights throughout the month of March from Germany to Ukraine, from Malta and Croatia to North Macedonia as well as from North America to Hungary in co-operation with governments and organisations in order to bring passengers back to their home countries.
“Wizz Air is operating flights between China and Hungary in order to deliver medical equipment such as protective gear and coronavirus test kits ordered by the Hungarian government.”
