I just got rebooked from my cancelled QR936 flight departing on June 25th from DVO to DOH to flight QR926 departing from DVO to DOH on June 26th. Was the perfect option as I don‘t mind spending an extra day in Davao City.
It seems like QR is resuming operations to DVO in June. Currently flight number QR926 belongs to the flight DOH - CRK. Looks like QR is changing up their flights into and from the Philippines.
