Air India will raise its Air India Delhi Sydney flights from 7 to 11 weekly services from 16 December 2026, according to schedule data reported by AeroRoutes. Part of the extra capacity comes from the Boeing 777-300ER, which starts on this route on 3 December.
For travellers in India, this means more choice on one of the busiest routes to Australia, especially around the year end holidays and university return season. Also, the larger aircraft should add seats on the daily peaks.

What the 777-300ER start means
The 777-300ER begins on AI301 and AI302 on 3 December, then goes daily from 1 January 2027. Because the aircraft type can change by date, your seat map may differ from what you saw when you booked. Executive Traveller has reported that Air India’s 777 flights to Sydney carry a first class cabin, but not on every flight, so check the cabin on your exact date.
How to plan around the change
First, confirm your flight number and date on the Air India website or app. Then, if you booked a flight that has been retimed, look for a rebooking or refund option in your booking. Meanwhile, remember that a morning arrival on AI304 may mean a long wait for hotel check in.
