I’m travelling on KL flight 0421 from Amsterdam to Muscat. This flight stops in Dammam en route for 45 mins ... I do not believe you get off the plane.
I am presuming I won’t need a Saudi transit visa for this but can somebody please confirm?
You do not require a Saudi transit visa for this itinerary even if you have to change planes.
TWOV (Transit Without Visa):
Passengers transiting through Dammam (DMM), Jeddah (JED) or Riyadh (RUH) with a confirmed onward ticket for a flight to a third country within 12 hours. They must stay in the international transit area of the airport and have documents required for the next destination. Only one transit stop-over in Saudi Arabia is permitted.
