Employees' time working for larger airlines is more likely to include layoffs, pay cuts and trouble with pension funding and other benefits, website founder George Hobica said. More of the larger airlines have personnel that have survived a company bankruptcy, he said.
"It's not surprising. The older worker has had a rougher ride," Hobica said.
