QR may or may not choose to ask you to pay the non refundable booking fees again, if they deem you are actually cancelling and booking a new ticket. Depending on your membership tier in QRPC, there may also be a cancellation fee if QR deem you to be cancelling your current ticket to book the new one.

The Doha call centre is open 24 hours and cheap to call using Skype or similar. The contact number for your membership tier will be on your QRPC dashboard once you log in to your account.

Alternatively you can send them a message via Contact Centre from your QRPC dashboard, selecting from the appropriate drop down message subjects, and telling them which flights you want to change to. If there is any fee to pay they will place the new itinerary on hold and tell you how long you have to pay this. There will then be a payment link on the Manage My Booking page for the reservation.
