Yeh the new T1 security area will be open April 15th but there's still a lot of other work to be done in T1. The whole retail project doesn't finish until Spring next year meaning that the airside area will be constantly being changed over the next 12 months with passengers being re-routed left, right and centre. It will be difficult enough to keep disruption to a minimum without the added pressure of PK and therefore I don't see this move going ahead just yet. In comparison, whilst the T2 redevelopment is now in full swing, the majority of the work is taking place on the now closed Mezzanine level and former Atlantic Suite. Both of these area's do not interfere with check-in or security and currently it is causing very little disruption. It is only the hoardings in check-in that are causing minor problems and as PK checks in mid afternoon when there are few other departures, it is not really an issue. In fact, I've heard on the grapevine that QR will be the first airline to move from T2 to T1 once their re-timed schedule kicks in.
