Boeing's South Carolina workforce passed 9,000 and keeps growing. Some are homegrown, many carried decades of Boeing service across the country — and a few Medicare rules treat those two groups very differently.

---

Boeing South Carolina is young by aerospace standards — the North Charleston 787 campus has only been building Dreamliners since 2012 — but its workforce isn't all young. The site grew to more than 9,000 workers, expansion keeps adding jobs, and engineering roles keep migrating from Washington State. That mix creates two kinds of Medicare stories: the local machinist or engineer approaching 65 after years on the flow line, and the 30-year Boeing veteran who transferred from Everett and will retire here in the Lowcountry — with benefits paperwork that spans decades and multiple plan structures.

Both stories run through the same federal deadlines. Here's the guide.

Still badged in at 65

Boeing is enormously past the 20-employee threshold: while you're actively working, the group plan stays primary and Part B can wait, penalty-free. Take premium-free Part A at 65 if you like — unless you're contributing to an HSA through a high-deductible option, in which case any Medicare enrollment cuts off your contributions. Aerospace pay also puts many Boeing households into IRMAA territory — the income-based Medicare premium surcharge, set by your tax return from two years back. A final year with heavy overtime, incentive pay, or a lump-sum payout can raise your Medicare premiums after you retire. Income dropping at retirement is appealable; few people know to file.

The transplant wrinkle: your benefits have a history

If you transferred from Puget Sound or another legacy site, your retirement picture may include pieces a newer South Carolina hire's doesn't — a frozen pension benefit from before Boeing ended pension accruals for nonunion employees in 2016, different retiree-benefit eligibility by hire date and location, and a 401(k)-centered package for the years since. None of that changes your Medicare deadlines, but it changes what's in your packet — and what questions to ask the Boeing benefits center before you set a date:

1. Any retiree medical benefit, subsidy, or HRA — or a hard stop? Eligibility often turns on hire date and legacy plan membership. Get your answer in writing, for your record, not a coworker's.
2. Pension elections, if you have a frozen benefit. Lump-sum vs. annuity interacts with taxes — and through IRMAA, with your Medicare premiums two years later. Sequence the decisions together.
3. Spouse under 65? Your retirement date is their coverage cliff. Bridge options need arranging before your last day.
4. Employer life insurance that shrinks or ends at retirement — replace it while you're still insurable at your best rates.

The clocks are the same for everyone

• 8 months after active coverage ends to enroll in Part B. Late means a lifetime penalty.
• COBRA doesn't stop that clock — and once you're 65, COBRA pays second to Medicare whether you enrolled or not. It's the most expensive "safe choice" in retirement.
• 6 months after Part B starts to buy any South Carolina Medigap plan with zero health questions. Decades of factory or flight-line work make that no-underwriting window especially valuable — it never reopens.

One more transplant note: if you moved to South Carolina already on Medicare — say you retired in Washington first, then followed the job or the grandkids here — your old Advantage or Part D plan doesn't automatically travel. A permanent move triggers a Special Enrollment Period to pick plans that work with Lowcountry networks like MUSC and Roper St. Francis. Don't assume the plan that worked in Everett works in Summerville.

Where we come in

• We read your Boeing packet — legacy pieces included — and turn it into a plain-English map of what you have and what it's worth.
• We build the calendar: Part B application, Medigap guaranteed-issue window, Part D start, all timed to your last day. No gaps, no penalties.
• We compare the whole South Carolina market as independents — Plan G, Plan N, Advantage, drug plans — checked against your actual doctors and prescriptions, including MUSC and the Lowcountry systems.
• We handle relocations — if you're arriving on an out-of-state plan, we'll re-shop it inside your moving-triggered enrollment window.
• No cost, no obligation. Carriers pay us either way; only the math drives the recommendation.

The bottom line

Whether you built your whole career in North Charleston or carried it here from Puget Sound, the Medicare handoff comes down to fixed deadlines meeting your specific paperwork. Both are manageable with a head start. If you or your spouse works at Boeing South Carolina — or just retired here from another Boeing site — send us the packet even a year or two out. The review is free, and you'll leave with your dates, your numbers, and a plan that fits the Lowcountry, not the one you left behind.
