BA is flying 3 fully booked 747s a day to LAX alone in August. Most flights will depart almost full- many overbooked. Don't even try for Bangkok and Singapore! HKG flights busy. Exactly why do you think the world will stop progressing? Don't you think people argued the same when the 747 doubled the seating capacity of long range jets in the early 70s? Do you really have the experience to judge?
