Neil - The purpose of this conference is primarily slot trading, so airlines prepare their wishlist and throw it into play. This year AC and KLM have proposed the most ambitious schedules. I believe that KLM proposed taking YVR to double daily with 767s, plus some major capacity increases in Asia (BKK to double daily, MNL to 14x weekly, etc...). Obviously they don't have the spare lift to fill all of these routes immediately, but its an indication of what they would like to do.
I'm pleased to see AC throw so much out on the table. My fellow Georgia Tech alumnus Robert Milton is doing something right, eh? Most of the US carriers, with the exception of Delta, have pretty much done nothing. US has changed nothing, AA wants JFK-FCO and JFK-BCN, UAL is doing nothing, NWAC wants KIX-ICN, CAL has EWR-GVA and thats pretty much it.
