Was there was last Sunday. Absolute chaos. Was on 2 different PNRs with 3 hours between arrival and departure. Took over 30 minutes to get through passport control, another half an hour for luggage to come out, 30 minutes to check in since no priority queue for UK and Africa departure clubbed together for 2 check in desks, and another 45 minutes to get back through passport control and take train to 4S and just about got to the gate 5 mins before boarding.
Last time we were there in February 24, it was a breeze but this time it was unpleasant.
