The medical is not the best I've ever had, but it's ok for a regional. United Healthcare PPO plan. I pay about $340 per month for myself and my family. The plan pays 80% after a $700 family deductible. I think for an individual it runs about $100 per month with a $350 deductible. There is a Flexible spending account available as well as dental and life insurance through Cigna. No vision insurance is offered.
The pass benefits are pretty standard Delta Connection benefits. Unlimited standby for you and your family after paying a $50/year fee. Transoceanic travel is limited to six days per year. Parents pay yield fares to travel. There are also interline agreements with most other airlines out there. We don't get buddy passes anymore now that TSH owns us.
We do have a 401k. Compass, er TSH, matches 50% of your contribution up to 6%. After 4 years this goes up to 8%, and after nine up to 10% (not that Compass will be around that long). You are 100% vested after completing your third year with the company.
As far as changes; other than the pass benefits, some administrative stuff like payroll, no longer having vision insurance, and a big legal battle between TSH and ALPA, no there haven't been any significant changes. Yet.
Feel free to PM me if you have any other questions.
