Sounds like a good day to fly... if loads are low enough, higher security might not cause much of a delay. Maybe bigger problems on transcon routes?
But, I don't think the loads will be as low as on 12/31/1999 (Y2K paranoia)... that evening, I flew BOS-JFK-ANC-ICN on a single KE 747 (I think they may have since dropped the BOS-JFK segment from the route).
We got a new crew at each stop. So, about 60 crew total, and one awfully empty 747, in the end got a total of around 20 passengers around the world. I wonder how much money they lost on that? At least they served lots of champagne. And, I got to fly BOS-JFK on "my own" 747

Not sure that will happen again...
