May 11 (Reuters) - Emirates, the world's largest long-haul airline, reported a sharp decline in annual net profit on Thursday.

The Dubai-based airline said profit fell 82 percent to 1.3 billion UAE dirham ($353.99 million) for the financial year to March 31.

Emirates said the weakening of all major currencies against the dollar cost the airline 2.1 billion in revenue.
