What Are Cape Air Baggage Fees and How to Add Baggage?

I actually flew with Cape Air last summer when visiting Martha’s Vineyard, and I learned a lot about their baggage policies the hard way. Initially, I assumed the baggage rules were like big airlines — but since Cape Air operates smaller planes, the limits are tighter. You get one small carry-on (under 20 lbs) and one personal item for free, but checked bags usually cost around $30–$40 depending on the route. I added mine later because I forgot during booking — and honestly, the easiest way was just calling their support at 877-764-3622.


The rep was super friendly and walked me through how to pay for my checked bag, plus confirmed the weight limits. It literally took five minutes. They even adjusted my flight details when I had to shift my departure time due to weather delays. So if you’re flying Cape Air, I’d definitely recommend calling 877-764-3622 before your trip. You can add baggage, double-check fees, or even cancel and rebook right there. It saves a ton of time compared to guessing online. Overall, it’s a smooth process once you know the limits — just plan light and call ahead!
 
I recently flew with Cape Air from Boston to Martha’s Vineyard, and figuring out the baggage situation was easier than I expected once I went through it myself. When I first booked my ticket, I didn’t realize that Cape Air’s planes are smaller, so their baggage limits are stricter than major airlines. Each passenger can usually bring one small carry-on and a personal item, but checked bags have specific weight limits (usually around 50 lbs) and extra fees if you go over.

Here’s what I did to add baggage: after booking my ticket, I went to the Cape Air website and logged into “Manage My Trip.” There’s an option to add checked luggage there — just select how many bags you’re bringing and pay the fee online (which was cheaper than paying at the airport). If you’re unsure or have special luggage, you can also call their support team directly — they’re super helpful and quick to confirm everything.

I’d recommend adding baggage in advance since space on the plane is limited. It saved me a lot of time and stress at check-in. Plus, having everything pre-booked makes the flight day so much smoother.
 
If you’re flying with Cape Air, here’s a quick breakdown of their baggage fees and how to add checked bags — based on my recent experience.

Fees & allowances

  • One personal item and one carry-on are free.
  • Checked bags cost: first bag up to 50 lbs is $30, second is $40, third is $80. If any bag is 51-70 lbs there’s an extra fee (e.g., +$80) on top.
  • Max size for checked bags is 62 linear inches and max weight 70 lbs.

How to add a bag
When I booked, I hadn’t planned on checking luggage. At check-in I realized I needed one checked bag, so I just told the Cape Air agent at the counter and paid the fee right there. If you prefer to prep ahead, you can call their number and ask to add a checked bag early. For example, if you call 877-764-3622 ahead of time they’ll tell you the fee for your route and how to handle drop-off.


Heads-up
Because Cape Air uses smaller planes on many routes, overhead bin space can be limited — so checking a bag earlier is smart. Also, make sure you check baggage rules for connecting flights with partner airlines because if your first flight is Cape Air, their fees apply.


Hope your trip goes smoothly and you don’t get surprised at the airport!
