Japan's two biggest airlines on Tuesday posted a significant recovery in profits in the April-September period, as travel demand continued to pick up amid the removal of COVID-19 restrictions in the country.

ANA saw its group net profit more than quadruple from a year earlier to ¥93.21 billion ($620 million) in the six months, while japan Airlines posted a consolidated net profit of ¥61.67 billion, a record high for the first half since the company relisted on the Tokyo Stock Exchange in 2012.

Helped by an increase in both domestic and international travelers, ANA said its operating profit also more than quadrupled from a year earlier to ¥129.74 billion, a record high for the six-month period. Sales grew 26.8% to ¥1 trillion.
