But why is Lufthansa the only carrier to order the -8 when every one else has gone for the 380,
Actually a few other airlines have ordered the 747-8i like Korean and Air China as well as (I believe) Arik Air of Nigeria although I doubt they will ever take delivery.
then look at SIA, if the aircraft was so bad why have they just ordered 20 more
Our own CEO has stated that he personally wonders about SQ's strategy of buying so many A380s and said words to the effect of "I wonder if he (SQ's CEO) regrets buying so many A380s."
