Ha thanks - though it's not this Sunday (just saw that my post is ambiguous on this point) it's not far away! I'll try to report back on the experience - Syd flight is on the same ticket so hopefully that protects me some, obviously though it would be more painful in terms of options if I have to be re-booked and take a later flight (presume higher chance I won't be able to fly business if any of next flights are fully booked). But I hope it's all academic..
