We went through at the end of Feb and it took ages!
When we landed the halls were so busy that they did not let us off he plane for 20mins.
Hen once we got into the hall we were queuing for an hour & a half to go through immigration.
Most of the lines were assigned to prioritising internal flights and then once those lines were clear they added more desks for international passengers.
I hope it was a bad day and that's not how it will be from now on.
