Can I use the Miles earned on my current flight towards an instant upgrade on the same flight?

You will need to have sufficient Skywards Miles in your account at the check-in desk or on board to get an instant upgrade. As Miles are only credited to your account after you complete a journey, we cannot factor in the Miles earned on the journey you are currently taking.
