Hawaiian Airlines is offering double miles on flights from their North American gateway cities to both Brisbane and Sydney, the two destinations they serve in Australia. The deal is valid on all bookings made via http://www.hawaiianairlines.com/SpecialOffers/Pages/Sept-Australia-Double-Miles.aspx during the month of September; travel must be completed by March 31, 2013.
Depart from New York, NY, Las Vegas, NV, Los Angeles, CA, Oakland, CA, Phoenix, AZ, Portland, OR, Sacramento, CA, San Diego, CA, San Francisco, CA, San Jose, CA, or Seattle, WA and connect on to Sydney or Brisbane on the next available flight (no extended stopover in Honolulu) in order to be eligible. The double points are for award redemption only, not for Pualani Gold or Platinum elite status.
