I do both ways on SYD-AUH. didnt check the other routes
Planning our trip for May 2016 and just 1 day shy of the booking window opening for MLE-AUH-SYD. The only Guest First seats I am seeing in the month of April 2016 are on the 77W (where as last night there was availability as late as April 23/24 on the A380). Also checked AUH-BNE on the B789 and no Guest First at all for the month of April. Had planned to book it in J and wait for F to open up and reissue the ticket for The Apartment.
May need to recalibrate our plans.
