Chief executive Jozsef Varadi said the budget carrier expected to operate at around 90% of 2019 capacity in July, and 100% in August.
However, he cautioned against making any firm predictions for winter owing to an operations environment dependent on "unpredictable government decision-making".
Varadi’s comments came as Wizz posted a €114.4 million (£97 million) loss during its first-quarter (three months to 30 June 2021), a period during which the airline was able to operate only a third of available capacity.
"The first quarter remained challenging, as mobility restrictions continued to be a major barrier to international travel," said Varadi.
