If you're a Gold or Platinum frequent flyer with Qantas, that's a big reason to not use rival airlines. Virgin Blue has latched onto that thinking, offering free upgrades to its Velocity Gold program for those Qantas members.
Australian Business Traveller reports that a promotional deal from Virgin Blue offers a full year on Velocity Gold, its top tier program which includes free lounge access and additional luggage perks, for Qantas Gold and Platinum members. Signing up for lounge access with any airline can be an expensive undertaking, so this is a handy bonus if you want to be able to alternate between airlines depending on price and still get access to lounge facilities.
Hit the link for full details of the application process; the deal is running until the end of November. For other ways of getting cheaper lounge access, check our full Road Worrier guide.
