The number to keep an eye on is how much debt is retired. That can often influence the declared profit. I suspect high 800 to low 900 million for the half depending on that debt number.
I reckon further 787 orders will be at the full year at the earliest when the lead time comes due for the subsequent slots to the first 8 already ordered. If they do announce extra airframes then that means an accelerated arrival schedule and all hell will break loose in training and recruiting.
Still reckon it's too early to announce 737 replacement or A320 family (particularly A321s for trunk routes or A319s for regional stuff) in the medium term.
Less than a week and we'll know.
