Major airlines worldwide diverted, delayed, or cancelled flights after Israel struck military and nuclear facilities in Iran, prompting Tehran to retaliate with drone attacks. The escalating tensions led to the closure of airspaces in Israel, Iran, Iraq, Jordan, and Syria, disrupting global air travel.

Air India was forced to turn back two flights—New Delhi-Vienna and Mumbai-London—mid-journey as they were about to enter Iranian airspace when Israel launched its attack. A London-New Delhi flight was rerouted over Iraq, arriving an hour late. The airline diverted or recalled 16 flights between India and destinations in the UK, Canada, and the US due to the crisis.

Emirates, the Middle East’s largest airline, suspended flights to and from Iraq, Jordan, Lebanon, and Iran. Similarly, Qatar Airways temporarily cancelled services to Iran and Iraq, citing regional instability.

Air France halted flights to Tel Aviv after Israel closed its airspace, stating passenger safety was its "absolute priority." Lufthansa suspended Tehran flights until July 31 and extended its Tel Aviv flight ban. Its subsidiary, Swiss Airlines, paused Tel Aviv flights until October 25 and Beirut flights until July-end.

Russia’s aviation authority, Rosaviatsiya, barred airlines from flying over Israel, Jordan, Iraq, and Iran until June 26 or until further notice.

Abu Dhabi and Dubai airports warned of significant disruptions, with Dubai citing delays and cancellations due to closed airspaces in Iran, Iraq, and Syria.
