Lots of low fares available from the West Coast to Australia and New Zealand. To find the cheapest prices, your best bet is Momondo. The lowest prices will be on Qantas Airways and United Airlines with availability in May and August through November. Here’s a few examples of the prices I found:
Los Angeles (LAX) to Auckland (AKL), New Zealand $619 Non-Stop
Los Angeles (LAX) to Melbourne (MEL), New Zealand $646 Non-Stop
Los Angeles (LAX) to Brisbane (BNE) Australia $653 Non-Stop
San Francisco (SFO) to Sydney (SYD) Australia $650 Non-Stop
These are great prices that would have probably been touted as mistake fares a while ago, but this post is mainly for west coasters. I was able to find fares priced in the $600s only from LAX and SFO.
Keep in mind that these are long flights, somewhere between 12 and 15 hours, and you’ll be flying in Economy class. It might be more bearable in Economy Plus with United if you have status.
Also check the find print on the booking site for cancelation rules.
