Was in transit with Emirates and exclusively in Terminal 3. OK so it looks impressive from outside and it is impressive inside but when your inbound flight is delayed and you have to get to your outbound connection in 20 mins it is not easy. The airport is too large and there should have been more thought put into how passengers get around in transit. We had to go from our gate to security then all the way back out to the gates. There were large queues at security and there was no allowance for the large group of passengers who were rushing for the connecting flight. There were very long queues at security. The duty free areas were OK but the stalls in the middle of the corridor/walkway meant that with passengers going in different directions along the narrower walkways it became congested at times. The airport could do with more seating and perhaps reclining/flatbed seats at the gates. The airport toilets could do with being cleaned more often as there was always a lot of water/fluid on the floor.
