About

Cape Air (operating as Hyannis Air Service, Inc.) is one of the largest commuter airlines in the United States, headquartered at Cape Cod Gateway Airport in Hyannis, Massachusetts. Founded in 1989 by pilots Dan Wolf and Craig Stewart with investor Grant Wilson, the airline began with a single route between Provincetown and Boston. Today, Cape Air serves over 30 destinations across the Northeast, Caribbean, Montana, and Midwest, carrying more than 500,000 passengers annually.

Cape Air is one of the largest participants in the Essential Air Service (EAS) program, a federal initiative that provides subsidized air service to rural communities that would otherwise lack convenient access to the national aviation network. This makes Cape Air a vital transportation link for many small communities across the United States.

The airline is partly employee-owned and maintains a workforce of approximately 700 people. Cape Air is not a member of any airline alliance but maintains codeshare agreements with JetBlue and United Airlines, providing seamless connections to larger networks. In September 2024, JetBlue and Cape Air enhanced their long-standing partnership to include TrueBlue loyalty benefits.

Tips & Tricks

Before Booking

  1. Book through JetBlue for points - If you're a TrueBlue member, book Cape Air flights through jetblue.com to earn points and have protection for connections.

  2. Check EAS eligibility - Flights to EAS communities often include free first checked bag and may have lower fares.

  3. Weather flexibility - If flying to islands or Montana in winter, build extra time into your itinerary for weather delays.

Packing

  1. Pack light - Small aircraft have strict weight limits. Your bags will be weighed at check-in.

  2. Essential items in a small bag - Keep medications, valuables, and electronics in a small personal item. All larger bags are checked planeside.

  3. Measure your sports equipment - Tecnam aircraft have tighter size limits (42" max) for skis and fishing gear than Cessna/Islander (70" max).

  4. Bring earplugs - Propeller aircraft are louder than jets. Earplugs make for a more comfortable flight.

At the Airport

  1. Arrive early for weight check - Cape Air must weigh all passengers and bags for aircraft balance. Allow extra time.

  2. Use the restroom before boarding - There are no lavatories on Cape Air aircraft.

  3. Bring layers - Small aircraft cabins can be warm on the ground and cool at altitude.

During Your Flight

  1. Enjoy the views - Every seat is essentially a window seat on 9-passenger aircraft. The low-altitude flights offer spectacular scenery.

  2. Bring snacks and water - No food service. Most flights are short, but have something just in case of delays.

  3. Download entertainment - No WiFi or screens. Load your phone or tablet before departure.

Island Travel (Cape Cod, Caribbean)

  1. First flight out - Morning flights are less likely to be affected by afternoon fog (common on Cape Cod) or Caribbean weather.

  2. Alternative routes - If a flight is cancelled, ask about alternative routing. Cape Air often has creative solutions using their network.

  3. Ferry backup - For Cape Cod islands, the Steamship Authority ferry provides an alternative if weather grounds flights.

Connections

  1. Allow generous connection time - Small aircraft delays are common. When connecting to/from larger carriers, allow at least 90 minutes.

  2. Book on one ticket - Always book Cape Air connections on the same ticket as your mainline flight for rebooking protection.

  3. Check codeshare flight numbers - Cape Air flights marketed by JetBlue will appear as B6 flight numbers but are operated by Cape Air.

Montana EAS Routes

  1. Limited frequency - Most Montana routes have 1-2 daily flights. Miss your flight and you may wait until the next day.

  2. Free first bag - Billings departures include free first checked bag.

  3. Confirm operations - In severe winter weather, confirm your flight status before heading to the airport.
