Emirates, the Middle East's largest airline, has had a better first half in the current financial year than the same period a year ago when it reported a 75% decline in profits. 

"The six months were a lot better than this time last year," Emirates airline President Tim Clark said at an aviation security conference in Dubai. 

The state-owned, Dubai-based carrier is expected to report its results next month for the six months ended September 30. 

Results a year ago were affected by a strong dollar and tougher competition as it filled a lower percentage of seats on a year-on-year basis. 

This year, Emirates has had to contend with travel restrictions imposed by the US which mostly impacted carriers in the Middle East, though have since largely been lifted. 

The airline cut frequencies on some US flights in a response to those restrictions weakening passenger demand.

Clark said demand had fallen by around 15-18% on US flights, though the airline had just had "a very robust summer" there.
