some off what you is true, unfortunately flight hours won’t go done. EK flew the 380 pre covid with a crew factor of 9 finding the left seat constantly in the 100-110 hr a month perfectly Managed with your leave (if twice a year) to manage your yearly block time.
this is and will stay the standard. eventually they will increase the over time limit back into the 90 to manage.
if you will see all the 42 days of leave granted will only show the future. So far before covid it was rare you see all your leave days and in some case leave at all.
