QR website vs QR Cargo
 

Hi there

I have a booking again in May/June and the aircraft types on my booking (QR website) and QR Cargo website is different for 3 out of 4 segments.

QR1366 12/05 (same B777-200LR Qsuite)
QR836 13/05 (Booking B777 Qsuite/ QR Cargo A380)
QR837 02/06 (Booking B777 non-Qsuite/ QR Cargo A330)
QR1365 02/06 (Booking A350 non-Qsuite/ QR Cargo B777)

Which is accurate?

With QR at the moment whatever is at the gate on the day.

😅
I'm happy with anything besides the A330..
fingers crossed

QR's website is more accurate in showing what aircraft type is assigned for that flight, the QR Cargo website is useful to see what configuration you will get (i.e. 77K, 77P, 77I) but only for the next month, after that it is usually a placeholder.

IF QR cargo says B777 and QR website says A332 for the same flight a week from today, which one should I trust?

On the flights I've been tracking lately (and it's a VERY small sample), qrcargo has been correct.

QR1366 12/05: plane
QR836 13/05: plane
QR837 02/06: plane
QR1365 02/06: plane

:D

I second this. I have seen QR Cargo updates that incrementally affect next 15 days or so. These are then accurate barring last minute operational disruptions.

QR Cargo tends to update the aircraft types first, especially flights from Doha, sometimes even updated before passenger database (ie. Reservation websites, seat maps and timetable).
Changings showing on the passenger database are confirmed, but there are always last minute changes.

But it depends on whatever aircraft is avaliable in Doha before departure. It is getting more common to either switching aircraft type (ie upgrade a 777-300ER from non Q suite to Q suite or vise versa / 777-300ER to 777-200LR), or delay the flight for no longer than 3 hrs to wait the scheduled aircraft type arrive from somewhere.

To answer my own question: QR cargo was wrong and QR website right.
