Journalist or interested observer, you're a very long way behind developments in the western political economy if you're just now discovering these trends. These processes began around 1970 and in relation to your question, have essentially redefined the meaning of "employee".
Google "neoliberal" to start; then read David Harvey's "Neoliberalism" for a good overview of these trends. If you ask a question about, "wither pensions?" you will get an answer that is merely descriptive, but if you do a bit of research and start peeling away the layers you may begin to understand what has happened to ordinary employees, the loss of pensions being merely one aspect of how industry has set aside employees as expensive liabilities. Industry will of course not see it this way.
These views are not uncontroversial but any response that will have substance to it, to a question concerning pensions, wages and working conditions not to mention intangible matters such as employee loyalty, dedication and focus, will not be complete and will instead perpetuate limited understanding of the issues unless at least some of these notions are researched and explored.
To address your question directly, in the US, the airline industry has, largely though not exclusively through Chapter 11 procedures, slowly destroyed, (stolen, some would say) employee pensions. I suspect some European operators have learnt the lesson by example. The issues are not unique to the airline industry of course but your question was in relation to this industry. Google "Sullenberger" and "Congress" for an address that captures some of what is conveyed here. It does not seem to be available in pdf format anymore but the youtube video is available.
