On July 6, SriLankan Airlines flight UL504 en route from London to Colombo had to take a longer flight path from its regular journey as the Kuwait Air Traffic Control denied entry into their airspace as their primary radar was unserviceable.

The aircraft had to be rerouted via a longer route avoiding Kuwait airspace, the airline said in a statement.

Even though UL 504 had sufficient fuel to return to Colombo, as an additional precaution, a technical stop was planned in Trivandrum after coordinating with the Airline Operations Control Centre to refuel the aircraft in Trivandrum and flew into Colombo.
