I don't think this would be easy as it sounds, assuming perhaps SQ didn't want to rebook passengers onto J2 (Azerbaijan Airlines). Looking at the timetable, it's going to be tight to get people on a 5am LH departure. The BA & QR flight departs at 10pm (meaning a 21 hr wait!), OS at leaving 5pm, options are really restricted to one of 4 TK flights. If they were operating these flights (narrow bodies) at 67pc load factor, that's about 50 spare seats per flight, thus would take 9 such flights to clear the backlog! Then you've got to find seats from IST-SIN. It seems that sending a replacement A380 was a sensible option.
