I passed through Terminal 3 when flying from Istanbul to Luxor and was pleasantly surprised. On arrival the visa windows were well signposted and immigration quite efficient. I made my way to the Domestic floor without being hassled by anyone indeed there only seemed to be about a dozen people in the whole Terminal. Quiet clean plenty of places to sit or get coffee water and something to eat. On return from Luxor I just followed the signs for connecting flights and went quickly through security only to find my Egyptair flight to Istanbul was delayed by 55 minutes. But there were shops to look at and decent looking food outlets too.
