Is it still the case that reward flights on Qatar metal are the same price (Avios + taxes) regardless whether they're booked on BA or Qatar directly? I'm asking as I can simulate the price on BA but I can't see the final price on Qatar as I don't have an Avios in my account there and then it will only show the Avios needed but I can't continue any further with the booking process so I can't see how many taxes they add. (Avios are the same).
