No piles at all in evidence as I came through at 10pm last night.
In fact, contrary to the horror stories of T3 and T4 arrivals, T1 was surprisingly peaceful, with just 3-4 people in line at Iris, and a handful in each queue for a real passport man.
Only bummer was seeing EVERY moving walkway from the Europier broken/switched off, and it's a long walk from gate 54.
