I'd say because the pay is already low, and no one has more then 2-3 years of longevity. The cost structure has stayed low, but as people accrue longenvity it will go up. I'd also say that advancement opportunities at VA are probably as likely as advancement at UA. Airlines that are bleeding $$$ don't grow. Perhaps the more appropriate question is "Why don't you think they need to take 30% paycuts YET?"
