Hi

I am thinking of booking a QR reward flight in Business Class and the cost is the same (£ and avios) on both BA and QR websites.
I am trying to think if there are any pro/cons using either website. I note QR's cancellation fee is $25 upto 24 hours to departure and $100 3-24 hours to departure, which is better than BA's £35 upto 24 hours to departure.

Are there any other pros/cons?

Also is cancelling a reward flight on the QR website straight forward?

Thanks
