I'm at a GMR company. You are correct that most major airlines and charter services have a much better benefits package (YMMV at the regionals and LCCs). But compared to my acquaintances in other lines of work/careers, GMRs is pretty solid. They have have full compliment of health, dental, disability, life insurance etc. The premiums aren't the worst out there, and it's pretty decent coverage. It's not airline great, but it's decent compared to most of what's out there.
