Fog in DXB has led to many 24 December 2017 diversions and delays. As one example, EK412, the 1015 hours DXB - SYD took off at 1640. A380 A6-EUG should arrive on Christmas Day at 1242, 342 minutes late. This flight normally then operates a 'tag flight' to CHC.
Also on 25 December. the DXB - MEL EK406 should arrive at 1115 hours, 285 minutes late. The 0810 hours MEL - AKL 'tag flight' will be unable to depart until at least 1300 hours.
EK434 from DXB down to BNE should arrive on Christmas Day at 1017 rather than 0640; as it also then normally proceeds to AKL, that second sector's 0825 hours departure is unlikely to occur prior to 1200 'high noon.'
The DXB - SIN - MEL EK404 is showing as arriving MEL at 1026 on 25 December, a little more than an hour late but this elies upon a stay of under an hour in SIN, probably unlikely.
