The airline has resumed its Boeing 787 services after a worldwide grounding of the aircraft in January.
The airline's fleet of five Dreamliners was grounded earlier this year following a directive from both the Federal Aviation Administration (FAA) in the United States and Qatar's Civil Aviation Authority.
Qatar Airways Chief Executive Officer Akbar Al Baker was the first passenger to board the airline's reinstated Dreamliner 787, joined by President Boeing Middle East Jeffrey Johnson, Boeing's Deputy Fleet Chief David Silver and a delegation of regional and international media.
Over the next few weeks and months, Qatar Airways will launch new routes to destinations including Salalah, Oman (22 May); Basra, Iraq (3 June); Sulaymaniyah, Iraq (20 August); and Chengdu, China (3 September).
