Its fairly public knowledge that the schedule is for the 3rd runway to be completed in late 2021, a 2 year interim 2 runway operation on the outer 2 runways and all 3 runways operating in late 2023.
JRs have stalled that timeline a bit so its looking more like 2024, assuming it gets the final go ahead.

You won't get an argument from me there. What were they thinking???!!
