wamba,
don't get me wrong, i sympathize with everybody in PAL and am not enjoying the sight of this great company going down. i am also shocked at the behavior of management as you rightly pointed out with the way they portrayed the pilots as the greedy ones.
i'm afraid though that PAL's woes are not merely issues with people at the top, but more crucially, structural. the company itself is very similar to some legacy, formerly state-run airlines that have failed (such as JAL and Mexicana), namely, multiple fleets, uneven customer service standard, confused pricing and marketing strategy (they don't seem clear whether they want to compete with the LCCs or the Legacies), and most especially, key decisions take a really loooooooong time to make. throw in CAAP category 2 and you've REALLY got a problem.
it's also not a matter of filling up the plane, it's a matter of making sure you keep your cost competitive so that even if the plane is NOT full, you make a decent profit.
