There's no direct flight MIA-ADE, but in close proximity is Los Angeles to Hong Kong, which is 7260 miles. It takes Cathay Pacific 15hr 25min on a 747 to get to HKG. Going back to LAX takes 12hr 25min. (due to jetstream)

If you could fly direct, probably about 15 hours A 747 cruises at about 550 miles per hour, and has legs long enough to make the flight, so according to my calculator, about 14 1/2 hours

Miami-LA, ??? 2-3 Hours LA to Sydney or Melbourne even Brisbane 14 Hours Sydney/Melbourne to Adelaide 1.5 Hours approx from Brisbane to Adelaide 2 hours. So 18-19 hours flying time plus stoping twice at airports, it will be arround 22-24 hours Go to a travel agent or Qantas.com to find out. When u get to qantas website, go adelaide to Miami, not Miami to Adelaide thats the only way it will work

First you'd have to catch a flight to the west coast of USA.United fly from los angeles & san francisco to sydney or melbourne where you'd have to catch a connecting flight to adelaide.There are no flights that go straight to Adelaide from the US.The 22hrs mentioned in the first answer would be pretty close to the mark
