By that logic ... Tiger has a zero profit margin ... Jetstar has a significantly positive one .. so JQ pilots should be paid more than Tiger?
Tigerair has a negative EBITDAR margin. It is technically bankrupt. It can only keep operating because it is being funded by VA. If it was on its own - it would need to borrow cash in order to keep operating. The TT pilots don't know how luckly they are. That business would 'close up shop' without a debt funding source. But you introduced a different company into the discussion. I refer to JQ and QF. It seems you're looking for an 'industry standard' renumeration/terms and conditions package. Why should that be the case? Every company is different.
also ROI (return on investment) is the highest at JQ of any of QF groups, so for every dollar QF board invests in this Business unit, it returns them back the MOST profit.
ROIC would be the appropriate comparison measure. But important here to note is JQ does not invest in assets/infrastructure/services as much as QF, so they are poor comparisons. JQ needs to be benchmarked on a similar LCC business, where almost all assets (except for x aircraft that were purchased), infrastructure is leased and services subcontracted etc.
