You’ll want to act fast on this one – United has launched a sale on flights to Australia for under $550 roundtrip!  This appears to be an attack on Delta, as most of the lowest fares are departing from Delta hubs (Atlanta, Minneapolis, Salt Lake City, and Detroit), and flights are available to Sydney, Melbourne, and Brisbane.

Here’s an example of fares between Atlanta and Melbourne for July:

You can search flexible dates on ITA Matrix, and book directly with United.  If you book with United, you have 24 hours to cancel completely free of charge, so if you’re at all interested in this deal, I would recommend booking ASAP.  You can always cancel later with no penalty, and these fares could be pulled anytime.  They may be around for a few days, or they may be gone in an hour or two.

This is the lowest prices I’ve ever seen on flights to Australia, so don’t miss out!
