(Reuters) - Etihad Airways will scrap flights to Tehran on Jan. 24, the latest route to be dropped as the Abu Dhabi airline pursues a strategy review.

The airline launched the review in 2016 that has also seen it sell or step away from investments in foreign carriers.

Etihad’s five weekly flights to Iran’s capital will be reduced to two a week between Dec. 25 and Jan. 23, before it suspends the route entirely on Jan. 24, an airline spokeswoman said.

She declined to say why the route was being suspended, but said in a statement that affected passengers could switch to an alternative travel date between Dec. 25 and Jan. 23 or be refunded.

Since launching the strategy review, Etihad has said it would cut flights to San Francisco and Dallas-Fort Worth in the United States.

Britain’s top defence buyer Tony Douglas will join Etihad next month as its new group chief executive, as the airline rethinks its rapid expansion strategy.

Two of Etihad’s major foreign investments, Air Berlin and Italy’s Alitalia, filed for administration this year.

Douglas, who joins Etihad from Britain’s Ministry of Defence, has previously served as chief executive of Abu Dhabi’s airport company.

Etihad has made few details public about its strategy review, which since being launched has seen the departure of its James Hogan, its group chief executive who led the airline for a decade.
