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.
DD I think you nailed it with this statement. Life is too short to worry about upgrades etc. The airline industry is dynamic and ever changing and one simply doesn't know which way it will go. Live your life for now and prioritize your family and friends. Work to live not live to work. The guys that were complainers in the right seat are still complaining in the left.
I personally think that the A350 cancellation will be substituted with more 777's and A380's. I also think we are approaching an unprecedented time in Emirates history where for the first time there will be a bit of movement generated by retirements and resignations by an ever increasing "older" pilot group. Also new opportunities present themselves as the global aviation market recovers which will no doubt attract some. Bottom line, who can really accurately predict a time to Command or anything else for that matter.
