With what airline?
The one with the biggest fleet, if you speak to our engineers who have been here for long enough they will happily confirm that the 380 has settled down much quicker than the 777 as far as dispatch reliability go's.
777 when first introduced was a total 'mare, of course now it is a well sorted aircraft with great economies, but let's not open that can of worms again.
Over 3 years of flying the 380, have changed aircraft once, apart from that very few technical delays of any kind.
