KAYAK’s top tips for finding a cheap flight from New Delhi to Sydney

  • There are several ways to get to the Sydney business district from the airport; many people take the train, which is cheap and convenient but can be a hassle if you have a lot of luggage, or taxis, which can be fast and straightforward but are often expensive. An alternative is to use a private shuttle service. This option offers you the convenience and freedom of a taxi service but in greater comfort and at a much more reasonable price. You can either get a shuttle on arrival or book online before departure to benefit from the discounted online booking rate.
  • If you have a long wait at Delhi Indira Gandhi International Airport (DEL) before your flight to Sydney, you might enjoy visiting The Cockpit, a very realistic flight simulator that permits travellers to experience being a pilot. The Cockpit is located in T3 in the international departures section. Demand is high for this unique experience, so you should definitely book ahead if you would like to try your hand at flying.
  • Passengers with hidden disabilities can identify themselves at Sydney Airport (SYD) by wearing a sunflower lanyard, available at the Terminal 1 Airport Services Centre and Terminal 2 Airport Ambassadors desk. This entitles you to use special assistance lanes during security and passport control procedures.

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.
