PR210 from MEL to MNL departed the former nine minutes early on Wednesday 19 August 2015 and was earlier shown as expected into MMNL about half an hour early, around the 1510 hours mark.
However it diverted to CRK - a most unusual move - and has only just departed at 1744 Philippine time for a slow estimated 1841 arrival into MNL, the reason for the extremely slow last leg being a very large amount of congestion around MNL - even more than usual - with aircraft such as RP-C3344 operating 5J7296 and VH-QPJ operating QF19 (both from SYD) among the many aircraft either having been slowed down by ATC or doing laps in a holding pattern.
From what I can see the weather looks relatively benign but many flights ex MNL are an hour or two late - while not unprecedented to have two hour delays, this is somewhat unusual when there is not a typhoon or heavy rain.
UPDATE: FR24 is now showing the PR210 arrival time at MNL as 1808 but there are still a few aircraft ahead of it. QF19 is managing to arrive early, probably at 1805.
