When can I request an upgrade? You can request a Classic Upgrade Reward after you've paid and received confirmation for a ticket on a Qantas flight with a Qantas (QF) flight number up until 10 hours before departure on international flights and up until five hours before departure on domestic flights.

Yes, you can upgrade a Qantas flight after booking through several different methods, depending on your fare type and loyalty status. The most popular way is using Qantas Points for a "Classic Upgrade Reward." You can request this via the Qantas app or website any time after your ticket is issued. These upgrades are not confirmed immediately; they are typically processed based on your frequent flyer status, starting with Platinum One and moving down to Bronze, with notifications sent between 24 and 72 hours before departure. Another option is Bid Now Upgrades, where Qantas invites eligible passengers to "bid" a combination of cash and points for a seat in a higher cabin. If you are looking for a guaranteed upgrade, you can also pay the full fare difference to move to a higher class at any time, provided there is commercial availability. Lastly, if there are empty seats on the day of travel, Qantas occasionally offers "at-the-airport" upgrades for a fixed fee or points. It is important to note that "Sale" or "Discount" fares may have restrictions that prevent mileage upgrades, so always check the "Upgrade" button in your "Manage Booking" screen to see which options are active for your specific flight.
