Looks like the SQ 744s just keep returning to MEL!
This will be it's 2nd time since the A380 replaced it, it will compliment the existing A380 service ofcourse like last time, not long ago the 744 flights were replaced with the retro fitted 73A. Maybe not enough capacity for a 773? How many A380's are SQ getting this year & next year? What are the possibility of SQ placing another A380 to MEL?
