I came up with a moderately evil way to call up MPC call centre and check upgrades - key in my other boss's SL number to talk to an agent faster. I don't need to key in his PIN.
If available, I'll hang up and use my own number to book after hours. But I'm really on watchful waiting mode on those Sydney October J upgrade seats.
But if I need anything done on my own account (like hold seat booking/confirm redemption), I'm still stuck with those 90 minute wait times.
Using my own number, got diverted to voicemail again this morn. Left my own GR number and contact number, waiting for them to call back.....
