For top captain at HKE flying 50 hours its 15K less than COS18 tier one Captain. At least on COS 18 you can move up to CPT 4 which gives you an extra 32K. So the difference between top Captain is 47K. And that's for 50 Hours. If you fly more the difference gets bigger and bigger. All one can really do is hang around, laugh about it and when the time comes move on !!!!
