Flight chaos: what the escalating Middle East conflict means for your overseas travel

For those with an upcoming overseas trip, all eyes are on the US-Israeli war with Iran which is causing significant ripples here in Australia.

Global air travel was disrupted after Israel and the US launched attacks on Iran on Saturday, February 28.

Since then Iran's retaliatory attacks have struck neighbouring countries, including an Australian defence facility near Dubai on Tuesday, March 3.

Countries including Israel, Iran, Iraq, Kuwait, Qatar, Syria and Bahrain, closed their airspaces over the weekend.

More airspaces were closed completely (Jordan), partially (Saudi Arabia), or were said to be under emergency security control (United Arab Emirates) on Tuesday, according to FlightRadar24.

The Australian government's travel advice level remains at "Do not travel" for Iran, Iraq, Bahrain, Israel, Palestine, United Arab Emirates, Kuwait, Lebanon, Yemen, Qatar and Syria as at Tuesday, March 3.

Foreign Minister Penny Wong said impacts on major transport hubs such as Dubai, which have previously helped get Australians home during conflicts in the region, were making the situation more challenging.

She told journalists on Tuesday there were about 115,000 Australians still in the region.

Meanwhile, an ACT Policing spokesman said they had increased patrols at a number of locations in Canberra "as a result of recent events in the Middle East".

Globally, more than 2000 flights to Dubai and nearly 750 flights to Doha have been cancelled since Saturday, according to flight tracking website FlightAware.

Here are the latest updates for Australians planning to travel to and from the region (from Sydney, Melbourne or Perth) or have layovers in these countries on their way to other destinations.

All six Emirates flights operating daily from Sydney and Melbourne airports to Dubai International Airport have been cancelled.

However, three night-time flights from Sydney and Melbourne, to Dubai on Thursday, March 5, were scheduled to take off on time.

All six flights from Dubai to Sydney and Melbourne scheduled on Thursday also remain unaffected.

The airline's online statement on March 2 stated it would begin operating a limited number of flights and would accommodate customers with earlier bookings as a priority.

Emirates said customers who had been rebooked to travel on these limited flights would be contacted directly by the airline.

Qatar Airways has temporarily suspended all flights until the Qatar Civil Aviation Authority announces the reopening of the country's airspace.

The airline said it would provide another update on March 4 about 5pm AEST.

The Australian airline said it was closely monitoring "the evolving situation" and potential affects on flights.

In an update on Tuesday, Qantas said its flight QF9 from Perth to London may operate via Singapore for a fuel stop due to adjustments required on flight paths.

"There are no other impacts to Qantas operated flights, including flights between Singapore and London," the airline said.
