These are very interesting times, lots of changes. Historically fleet orders change and some get disadvantaged whilst others gain. If you are counting the places to upgrade then it is frustrating but second guessing deliveries is a fools game that only leads to disappointment as we have no control or influence of what gets ordered or delivered.
If you are waiting for the precious upgrade to fix all life's woes then after a short while you will be sadly disappointed. Fed up with night turns in the right hand seat then you will also get fed up with them from the left. The extra cash will wear thin after a wile.
Get a hobby, enjoy whatever is your thing and work to live. Control the parts of your life you have control of, or make a change. Don't be a victim of circumstance.
