Adds details on capacity shift and loss from paragraph 2 onwards
May 5 (Reuters) - Air Astana AIRA.KZ, AIRAq.L reported a first-quarter loss on Tuesday that widened nearly threefold as costs jumped after the Kazakhstan-based carrier shifted capacity away from Gulf routes due to the Iran war.
After the U.S.-Israeli strikes on Iran upended the aviation sector, the carrier cut Middle East capacity by 51% against planned levels for the quarter, halting flights to Dubai, Doha, Jeddah and Madinah.
It also reallocated capacity to Southeast Asian leisure routes and East-West transit connections.
Air Astana posted a loss after tax of $21.1 million for the three months to March 31, from a loss of $7.3 million a year earlier, as unit costs climbed 19.8% due to the company maintaining a cost base for higher planned capacity.
