You CAL guys need to quit discussing trade secrets here. Let the AMR and UAL people continue to blunder. Putting 777 non IGWs on JFK to HKG and diverting 3 times a week from BCN may be why they have more people on the street than CAL does.
If they are smart they'll take fuel off in BCN. After all, it takes fuel to carry fuel, so if you leave a couple grand behind you'll burn less by not carrying it all the way over the ocean right?
