We booked ARN-DOH-SIN-DOH-OSL during a sale.
QSuites went from (outbound/inbound) 0/1 to 1/1 to 1/0 to 0/0.
The first changes were good for us as they helped us get seats next to each other (in a suite) whereas the 359 cabin was fully booked, and we could also rebook the return flight to KUL-ARN in D class a day later for free.
But then the QSuites were taken away from the outbound again, which made us really sad because now we don’t have a single QSuites flight left and we’re out of rebooking options.
The last change was made exactly one month before departure.

Is this normal? Do they make the final decision a month before departure or was that a coincidence?
What are or chances of seeing another equipment change? QR944 on April 11.
