We already do.
No credit for RTB.
This is pure genius.
Sign on early morning
Taxi aircraft around all day then fly to tpe.
All for 2 hours credit.
Why stop there?
In between HAECO ferries, why not have unproductive pilots cleaning the cabin? Filling in for a few missing traffic officers? Doing the occasional oil change? Getting an aircraft setup for 3 crew long haul so they can simply sign on 5 mins before pushback?
The options are endless.
Cathay will never have to plan an expansion again!!
