Indian budget carrier IndiGo announced on February 3 that it has canceled all flights to and from Tbilisi, Almaty, Baku, and Tashkent until February 28 due to the evolving situation around Iran.

The airline said the cancellations were part of measures to ensure a safe and seamless experience for customers and crew. Customers can explore alternative travel options or opt for a full refund, The Caspian Post reports, citing bne IntelliNews.

IndiGo added that its plans remained under regular review as the situation continues to evolve, with further updates to be shared through its communication channels.

The cancellations affect routes through or near Iranian airspace. Several European carriers, including KLM, Lufthansa and Air France, have already suspended or rerouted Middle East flights since January 23 as the prospect of a US military strike on Iran raised serious safety concerns over regional airspace.

Germany advised all national carriers to avoid Iranian airspace until February 10, while the European Union Aviation Safety Agency warned airlines to avoid Iranian airspace due to risks posed by air defence systems and unpredictable military activity.

The USS Abraham Lincoln carrier strike group entered the Middle East on January 26, with US President Donald Trump describing the force as a "massive armada" and urging Iran to negotiate over its nuclear programme. Iran and the US are now expected to hold talks in Istanbul on February 6.

Despite the ban on flights to the Islamic Republic's northern neighbours, IndiGo does not fly to Tehran, however, the cancelled flights typically pass through Iranian airspace en route to Central Asia and the Caucasus.

IndiGo operates A320neo aircraft on these routes, which lack the range to take longer alternative routes that avoid Iran.
