The A380 burns 12% less fuel per seat. At 525 seats, that means it would burn 12 x 5.25 = 63 times less fuel per hour, or 6.3 times less fuel in 10mins
So it actually saved money by going around. (Plus what Mad (Flt) Scientist said)
I have to question the maths on this, if what you are saying is correct then would it not make sense for an airline to continually go around until in handsome profit ?
The comparison is that in a like for like situation if the competitor could occupy 525 seats then the fuel burn would be 12% cheaper. Thus the penalty of a go around would be the same for its nearest competitor less 12% - we then have to build in variations on occupency etc etc but that is their claimed ball park figure.
I am confused at what your saying ken, there is no saving as there is a fuel cost penalty for going around - its just a little cheaper than had it been one of the competitors aircraft - your post implies they have a saving by going around.
