Went through T2 last week (24th) and was amazed at the service. From leaving the car, checking in and passing through security took 20 minutes, admittidly it was mid morning but I expected increased security after what happened in the city centre. It was there but it wasnt readily noticable. Similar experience last night/this morning it took about 30 mins to clear immigration (they where pushing a lot of people through the e gates and they are a tad slow but the luggage was on the belt when we got to the hall so it was just a case of pick up and leave.
Interesting experience landing on 23L and back taxiing as well.
