Dubai-based Emirates airline on Tuesday posted a $5.5 billion annual loss, its first in more than three decades, after the coronavirus pandemic devastated the aviation industry, AFP reported.

The carrier said it received a capital injection of $3.1 billion from its owner, the government of Dubai, to help it survive the crisis.

The Emirates group was "hit hard by the drop in demand for international air travel as countries closed their borders and imposed stringent travel restrictions", said chairman and chief executive, Sheikh Ahmed bin Saeed Al Maktoum.

"No one knows when the pandemic will be over, but we know recovery will be patchy," he said in a statement.

The Middle East's largest carrier said that the fallout triggered a loss of 20.3 billion dirhams ($5.5 billion) over the financial year to March, after last year's 1.1 billion dirhams ($288 million) profit.

The airline, which was forced to temporarily suspend operations last year, saw revenue fall 66 percent to $8.4 billion.

Over the fiscal year Emirates carried 6.6 million passengers, down 88 percent from the same period in the previous year.

"The Covid-19 pandemic continues to take a tremendous toll on human lives, communities, economies, and on the aviation and travel industry," Sheikh Ahmed said. "Economies and companies that entered pandemic times in a strong position, will be better placed to bounce back."

In Tuesday's statement, it said the Emirates Group's employee base—which includes ground-handling firm Dnata—was slashed by 30.8 percent to 75,145 employees.

Before the virus hit, Emirates airline alone employed some 60,033 staff, including 4,300 pilots and nearly 22,000 cabin crew. The workforce has now shrunk to 40,801 staff.
