EDIT: Sale extended to 28 November.
Virgin have been having a sale for a while, and I've been looking to book Perth to Los Angeles (and was going to last week for ~$1500). Now, a week later, same sale, they have advertised PER to LAX for $1444 inclusive of tax, but I was easily able to find flights that totalled $1303.37 after selection. Amazeballs!
I'm leaving in May, returning in July. I don't have time to check every date, but for info: Outbound flight was marked at $686.96, and the return was $831.41. This adds up to $1518.37, but for some reason their system calculates the total price at $1303.37. I can confirm this is the amount I just paid, plus a $30 credit card fee. Avoidable if you use some other payment methods, but who wants to miss out on their free platinum travel insurance? =p
P.S. Two pieces of luggage up to 23kg included for ALL sectors. No stopover in Sydney at this price.
Also, advertised price SYD to LAX is more at $1,439!
