Before Covid the HKE package was a little better than COS18 and they were afraid that after Cx bought the company they would be put on COS18.
However the pandemic completely obliterated HKE flying schedule to almost zero, so everyone was out on a much reduced package, figures very similar to mentioned above.
As they move out of the pandemic and into a more fruitful flying schedule it will be interesting to see what they do with the package. They will have to increase it to recruit expat candidates but they can’t return to what it was before as that is better than COS18 and you can’t have your LCC being better paid than the mainline.
