Thanks for attaching the graph to tour post Mick
Totally backs up my point and discredits yours
By your own graph we have not been running 12 months unimpeded
We are in August 2022
By your graph we bottomed out in August 2021 at around 20% of 2019
Nov-Dec barely made it to 50% pre-covid and REX jet still grounded
This 50% remained for 2 months due to the beginning of omicron propped up by the holidays
This 50% lagged through February
March to August saw the main recovery which is
6 months 
And as for activity quadrupling when you are coming of such a depressed base, that is no surprise
As for break even
REX has continually stated that their 737 operating costs are lower that even JQ
What their actual break even is I really don't know, but 70% would be close to the mark
