Fast-growing Hawaiian Airlines boosted its profits 77.6 percent in the third quarter even as fuel costs continued to rise.

Parent Hawaiian Holdings Inc. reported today that net income soared to $45.5 million from $25.6 million in the year-earlier period.

Revenue jumped 20.5 percent to $549.3 million from $455.9 million.

“Our strategy of diversifying our revenue base through growth is demonstrating its value as we have seen some enormous variation in market performance across our network of late,” President and CEO Mark Dunkerley said.

Fuel costs increased 21.9 percent to $165.8 million from $136 million.
