Terrible experience will never fly Delta once more. Delayed flight with whole disorganization and inept crew who wouldn’t connect. An average direct flight from India to Australia can take 19h 02m, masking a length of 14982 km. The preferred route is New Delhi - Melbourne with a mean flight time https://businessbookmark.com/story3923150/how-much-you-need-to-expect-you-ll-pay-for-a-good-business-class-brisbane-to-london
