Beginning September 12th, 2012, all gold or higher status Delta medallions will receive priority check-in, priority boarding, priority bag handling, and priority security lines when flying Virgin Australia. Silver medallions will receive priority check-in and priority boarding on VA-operated long haul flights.
Anecdotally, I have been flying Virgin Australia on and off for the past three years, and they have always extended these benefits as well as lounge access to me as a Delta Diamond Medallion when flying VA within Australia.
If you’re a Delta Medallion, you may have already received this notice, unless your spam filter ate it…
