Cathay Pacific Airways on Wednesday reported its first full-year loss since the 2008 global financial crisis, dragged down by overcapacity, a strong Hong Kong dollar and mounting competition from mainland Chinese carriers.

Shares of Hong Kong's flag carrier fell almost 5 percent after the news. Cathay had warned its results for the second half of 2016 would be weak as it battles falling demand for premium class seats on long-haul routes. It now expects the outlook to remain challenging in 2017 as the headwinds continue.
