Wizz Air says it will suspend its Abu Dhabi operations starting Sept. 1. The Hungarian low-cost airline cited geopolitical instability, supply chain issues, and limited market access as key challenges.

Barclays (LON:BARC) has upgraded Wizz Air to “equal weight” from “underweight” and raised its price target from £9 to £11, citing the carrier’s exit from Abu Dhabi as a strategic correction, in a note dated Thursday.

Wizz Air Holdings Plc said it will suspend operations in Abu Dhabi amid persistent engine issues that have grounded aircraft, as well as geopolitical challenges and regulatory barriers as the budget carrier tries to keep costs under control.
