tourists and travelers are hardly a uniform group. A young single person, is different from a family with kids, which is different from a group of young people on a party trip. A young single person can often have a bag ready and depart directly from work; a family with kids may want to depart in the morning to be there super early; a group of young people hungover from last night's bender may want an afternoon flight. Not to mention, often you are picking between an optimal departure time and an optimal arrival time. For instance, I know people who love redeye flights to fly across the continental US, but I hate them because they mess up my sleep. The A380 is essentially a really big bet on a one-size-fits-all plane, for travel segments that rarely are.
