This is a good rumour I heard, which may change the use of reversers.
The company pays a set rate for undercarriage and tyres. So not using the reversers will put more strain on said undercarriage and tyres, costing the "company" that supplies them to EK more.
Now it is rumoured that the owner, or part owner of the company that supplies these items to EK is non other than AAR.
As I said , its a rumour, but where would you like the extra cost going, if in fact the rumour is true.
