The World Expo, which brought some 70 million visitors to Shanghai, coupled with solid growth in the Chinese aviation sector, have made 2010 a bumper year for the two passenger airlines that call Shanghai home. Boosted in part by its acquisition of Shanghai Airlines, China Eastern expects its 2010 to exceed its previous year’s by almost ten times. Meanwhile, China’s largest budget airline, Spring Airlines, also didn’t do too shabbily, nearly tripling its 2009 net income. And here’s some good news: In 2011, the carrier expects to open new routes to Japan, Taiwan, Macau and Southeast Asia. Yay for more cheap airfares!
