Emirates airline's profit slumped 69 per cent in the last year to US$237 million ($359m) despite record revenue.
The airline is the biggest long-haul carrier and was hit by higher fuel prices and slowing demand in the Middle East.
Although the 31st successive year of profit, it was the lowest since 2009. Chairman and chief executive of Emirates Airline and Group, Sheikh Ahmed bin Saeed Al Maktoum, said the 2018-19 financial year had been tough.
"Our performance was not as strong as we would have liked. Higher oil prices and the strengthened US dollar eroded our earnings, even as competition intensified in our key markets."
The increase in global airfreight demand from the previous year appeared to have gone into reverse. Emirates had seen travel demand weaken, particularly in its own region, impacting both the airline and data, its ground handling, cargo, travel, and flight catering services subsidiary.
