Excel and chicken innards!
Based on a very scientific method of first half results, chicken innards and wetting my finger and holding it in the wind, I predict the profit share will be 16 days + $6,000 which is derived from a profit of $6.3billion on turnover(net of recoveries) of $64.9billion. There are a lot of variables so margin of error is probably +/- $5billion on turnover!
For the cabin crew rumour of 4-6 weeks PS to be true we need profit to be $8billion - $9.5billion on that turnover. We will find out in a few weeks if my chicken innards can be relied on;-)
