We're seeing a huge nationwide sale to Australia today with fares in the $600s and $700s from nearly every airport in the US. Fares to Australia have come down overall this year, and although we've seen a few flash sales with better prices from major hubs, this is a widespread sale that covers many smaller airports.
Departures from the USA are available from late April through early December. If you want to stay down under for an extended period over the winter holidays, these fares also work if you depart in early December and return mid-January through the end of the booking schedule.
Outbound travel is blacked out in late July and most of October; Inbound travel is blacked out in late June, late December, and early January.
Travel is valid on Mondays, Tuesdays, Wednesdays, and Thursdays.
This sale is unadvertised and fares may jump at any moment.
This is nowhere near a complete list. Nearly every airport in the U.S. has flights to Sydney (SYD) or Melbourne (MEL) in the low $700s for travel during the months listed above. Some notable exceptions are major Delta and American hub cities but surrounding airports may be included.
Check flights from your city even if it's not listed here. Other cities in Australia may have lower fares than normal as well.
These fares include a carry-on bag, a personal item, and two free checked bags.
Advanced seat assignments are included.
Booking on some third-party sites may bring these fares down even lower. A few routes from Los Angeles (LAX), San Francisco (SFO), and Honolulu (HNL) have lower fares on Fiji Airways or Jetstar. The Fiji Airways flights can work out to be a great 2-for-1 deal if you also want to see Fiji. The same can be said if you want to combine a cheap flight to Hawaii with Jetstar's $408 roundtrip fare from Hawaii to Sydney for August/early September travel.
As an example, I found seats departing Buffalo BUF on Tuesday, December 10, returning from Sydney SYD on Thursday, December 26, for $733 roundtrip. That sounds like a perfect time to escape the cold in Buffalo and spend Christmas down under.
