Tokyo - Japan's All Nippon Airways (ANA) said on Thursday its net profit for the six months to September soared about 78% to $328 million, citing a Tokyo airport expansion.
The carrier said it earned ¥35.77bn ($328m) against a ¥20.07bn net profit a year earlier, while April to September sales rose 9.1% to ¥854.82bn.
The sharp improvement came as ANA expanded its international services, benefiting from a major expansion of Tokyo's downtown Haneda Airport, which it said helped offset a jump in operating expenses mainly due to the higher fuel costs.
A sharp decline in the yen has sent the price of fuel - often an airline's single-biggest expense - surging for ANA and rival Japan Airlines, which reports its earnings on Friday.
Operating profit for the first half year rose about 33% to ¥57.94bn, ANA said, while it also booked a one-off profit of ¥9.9bn as it changed the structure of its corporate pension scheme.
For the full-year to March, the airline kept its estimate of a ¥35bn net profit on sales of ¥1.7trn.
