Jeddah - Saudi Arabian Airlines faced a disruption of flights after it was hit by a system failure.
"Saudi Arabian Airlines (Saudia) informs its valued guests about flight delays across the network due to an unforseen system issue," the state-owned carrier said late Tuesday.
"As a result there are delays on some Saudia flights... the airline is taking all necessary measures to resolve the matter as quickly as possible."
The disruption comes as the kingdom prepares to host the annual Haj pilgrimage.
So far more than one million pilgrims have arrived in the kingdom, according to state media.
