I am not some airline ceo, nor trying to pretend to be one... but as a singapore airlines cabin crew, i can attest that there are some airlines out there (like sq) that really need very large aircrafts, such as the a380s. i have been flying for sq for almost 10 years now and i have seen the increase of pax... for e.g. the sin-lhr leg. it did go down for a little bit after 9/11 or during the sars crisis
