The USA use a different method is my understanding - Like Hell they allow 0.04% as we have in Oz - stupid to mention.
From memory more than 100 ish pax were put on a later flight - very light for a 380.
Did Geoff give all this accurate info?
My guess, 100ish got on next available flight to fill it, new crew arrived to take rest departing 16ish hrs after original was meant to and with remaining paxs that got the lay over.
Sad days indeed if a 380 runs around with 100ish pax. Or NO pax with a valid crew??
