If you search Timatic for a transit in Saudi Arabia, it says this
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.
What does it mean by the last sentence? Does it mean that a passenger can avail TVOW facility only on one leg of the journey?
Some people are of the view that it means only 1 stop-over is allowed and no domestic connection is allowed. But that is the same for an airiside TVOW permission by any country. No airside transits allow domestic connections. Then why is there is special note for Saudia Arabia? Why not UAE for example?
