I consider any price under $1,000 to be a good deal for nonstop flights from Australia to the US, so the fact you can choose from Virgin Australia, Delta and American Airlines is a big win!
These prices are available for departures on a Monday, Tuesday or Wednesday during Term 4 of 2018 and Terms 1 and 2 of 2019, i.e. they are not available during school holidays.
Economy Class on the specific planes flying this route feature 31 inches of seat pitch (the distance between your seat and the one in front of you) on Delta and AA and a more spacious 32 inches with Virgin Australia.
I also found flights departing from Melbourne on Virgin Australia from $974 but only for departures on Wednesdays.
Arrive: Los Angeles
Dates: During school terms until 12 June 2019
Airlines: Virgin Australia, Delta and American Airlines
Cost: From $989 in Economy
I find Google Flights a useful tool to compare prices across dates but then to book through the airline or Expedia (see below).
Where to credit points: I would recommend crediting your Virgin Australia flight to Velocity or KrisFlyer; your Delta flight to Velocity; or your American Airlines flight to Qantas, American Airlines AAdvantage, Alaska Airlines Mileage Plan, Cathay Pacific Asia Miles or British Airways Avios. Read more in our guide to where to credit points.
Lounge access: Priority Pass members can access four eateries in Sydney’s international terminal regardless of airline; American Express Card Members can enjoy a relax in the American Express Lounge regardless of airline; Velocity Gold and above members gain access to the Etihad Lounge if flying Virgin Australia or the SkyTeam Lounge if flying Delta; Qantas Gold members can go to the Qantas International Business Lounge if flying American Airlines
SkyTeam Lounge Sydney
Booking link: you can book directly with the respective airline or, whilst not much, you can earn 0.7% cashback (~$7 on this purchase) as well as Expedia Rewards points if booking through Cashrewards’ Expedia link. If flying Virgin Australia, I would recommend trying one of these discount codes for up to 10% off
Airfare deals are typically only available on limited dates. Fares may disappear quickly, so we suggest booking as soon as you are confident in your travel dates.
