SQ at DXB

[A300Man]

I have noticed that SQ have been sending a 744 on a few occasions recently into DXB, as opposed to the regular 772 or 773. (I have noted it mainly on Friday's). From a distance, I initially assumed it to be a Mega-Ark. However, closing-in on touch down, it became apparent that it was a pax jet.

Anyone know if this is a permanent feature on the timetable, or just a temporary replacement.

Thanks.
