Horizon- employee is covered at no cost to employee with medical/dental/vision (though not good vision coverage). Also have life insurance equal to 1 year pay at no cost.
About $300/month to cover my wife and son with medical/dental/vision.
One thing I have liked with Horizontal is that Alaska Air Group is self-insured. They pay Blue Cross to manage air group money for health costs. Kind of nice as since it isn't Blue Cross's money and they don't fight over coverage.
