Do you check if your Qantas flight is eligible for a "Bid Now" upgrade?

Qantas has introduced a flight upgrade initiative called "Bid Now" that allows members of their frequent flyer program to place a "bid" to get their Economy class bookings upgraded to Business class. 

To make a bid, follow these simple steps:

• Within 7 days of flying, visit the "Bid Now" page (if you've booked more than 7 days in advance, use FollowUp Then to set a reminder for yourself)
• Enter your last name and booking reference into the field provided
• You will be asked to nominate a "bid" (set amount frequent flyer points and/money) for the upgrade, as you would in a blind auction
• Within 24 hours of the flight, you will be notified if your bid was successful
