Dear Anna
You seem very fond of quoting "Industry Standard" as an excuse for reducing our CoS, salaries, housing etc. Have you considered charging passengers for each check in bag? Perhaps HKD$100 for the first bag and then HKD$200 for any subsequent bag? This could replace the fuel surcharge you tried so hard to hang on to. If you are wondering how much such a bag surcharge might make, watch this video:

Cut and paste into your browser. Sorry. Related aviation content from 6:30.
Anna: That would make you far more than the 10% you are looking to steal from me.
Sincerely
ARSE
