The dinner was the 'official' launch celebration and was planned a long time before the first flight.
Although there is lot's of talk of it going daily or wishing it goes daily, the inside word is not before October i.e W15, in fact the slots for days 3, 5 and 7 that were applied for some time ago starting October have just been handed back!
Also Boston is a new route starting soon as well. The last of the 777-300ER orders finish this year, Oct I think, another new one this month. Then there will be a gap until the A350 deliveries start in 2016.
