I booked a flight for DOH - SIN travelling in March 2023 that was Qsuite originally, with seats selected at the time of booking, which has since been swapped to 787-8 without any email from QR to notify the change.

When I searched for other flights for DOH-SIN, it seems that is no longer served by any planes with Qsuite? That route is only served by 787-8 and A359 with no Qsuite mentioned anywhere though the photos for the 787 are shown as Qsuites (they were 777 before the swap) but non-Qsuite photo shown for A359.

I wonder if DOH-SIN is now a non-Qsuite route?
