On days not mentioned above, a B747 without individual TV entertainment consoles in Economy Class will be used.  From Jan 16, 2012, A340-600 aircraft will operate the service which will provide all Economy passengers with individual In-Flight Entertainment. 
 
The basic difference between the A340-600 and the B747 is in the seat capacity which can be summarised as follows:
 
B747:  Royal First Class 10 lie-Flat seats / Business Class 14 Seats / Eco class 325 seats
A340-600: Royal First Class eight flatbed seats / Business Class 60 Seats / Eco Class 199 seats
