Avios reward booking booked through BA travelling on QR

[seemab]

Hello

Advise please

Booked my first reward redemption through BA using avios travelling business class / first on QR on the following route . Me and my wife travelling

LGW-DOH-HKG , business and then First DOH-HKG in May

Flights look very busy . my friends who have travelled on redemptions on BA have been downgraded in the past when flights are busy

How likely are QR to bump pax or downgrade pax travelling on avios tickets booked through BA . If it happens will QR rebook back in business / first or will they palm me off to BA

Anyone had any experiences with downgrades on QR on BA avios tickets

Any feedback would be grateful
