As Qantas frequent flyer members know well, snaring a business class or premium economy award seat booking can be difficult because of their scarce availability relative to economy class. For the first time, the airline will now give customers who book a "classic flight reward" seat in economy class a shot at an upgrade to business or premium economy using points. "We're constantly evolving our offer based on the feedback our members provide us and this is another example of how we've responded to their requests for more ways to use their points on flights," a Qantas spokeswoman said. The new option won't be a bargain – it will require more points than an initial award booking in premium cabins. For example, an initial Sydney-Los Angeles business class award booking would require 96,000 points. <br/>
