Etihad Airways will scrap flights to Tehran on January 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 December 25 and January 23, before it suspends the route entirely on January 24, according to an airline spokeswoman.

She declined to say why the route was being suspended.

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