What is COC on Boeing 777? (Customer Originated Change)

The Customer Originated Change (COC) process is an essential part of Boeing’s customer satisfaction strategy for the Boeing 777 aircraft. COC refers to the modification and customization requests made by customers, which are then incorporated into the design and production of the aircraft. This allows customers to have a more personalized and tailored aircraft that meets their specific operational needs.

With the COC process, Boeing ensures that customers can customize various features of the Boeing 777, including cabin layout, interior design, avionics systems, and seating configurations, among others. By offering this flexibility, Boeing aims to optimize the aircraft’s performance and enhance the overall customer experience.

Benefits of Customer Originated Changes

The COC process brings several benefits for both Boeing and its customers. Here are some of the key advantages:

1. Tailored Solutions

Customer Originated Changes enable airlines and operators to customize the Boeing 777 to meet their specific requirements. This flexibility allows them to optimize the aircraft’s performance for their unique routes, passenger needs, and overall business objectives. By tailoring the aircraft’s features, such as cabin layout and seating configurations, airlines can enhance passenger comfort and improve operational efficiency. This level of customization ensures that the aircraft aligns perfectly with the operator’s business model and differentiates their services from competitors.

An example of a COC-related change is seen in the interior configuration of the Boeing 777-300ER aircraft delivered to Singapore Airlines. The airline opted for a unique cabin layout featuring a luxurious first-class suite, spacious business class seats, and an economy class with additional legroom. This tailored design has allowed Singapore Airlines to offer a premium travel experience and maintain its reputation for excellence.

2. Improved Operational Efficiency

By incorporating customer-requested changes into the aircraft, the COC process enhances operational efficiency for airlines and operators. For example, customization of avionics systems allows the integration of specific technologies or navigation equipment preferred by the customer. This customization can lead to improved navigation accuracy, fuel efficiency, and operational reliability.

In addition, COC-related changes in seating configuration can optimize the use of cabin space, enabling airlines to maximize revenue potential. By offering different seating options, such as premium economy or extra-legroom seats, airlines can cater to the diverse needs of passengers and generate additional revenue streams, while still maintaining a high level of comfort and satisfaction.

An example of improved operational efficiency through COC is demonstrated by Emirates Airlines, which ordered the Boeing 777-300ER with a customized cabin layout that includes a spacious first-class cabin, business class seats, and a larger economy class. This tailored configuration has allowed Emirates to efficiently serve their high-demand routes and maximize their operational profitability.

3. Enhancing Customer Experience

Customer satisfaction is a top priority for Boeing, and the COC process plays a crucial role in enhancing the overall customer experience. By customizing the Boeing 777 to meet specific customer requirements, airlines can offer a unique and differentiated product to passengers.

Features such as personalized cabin interiors, in-flight entertainment systems, and seating comfort contribute to an exceptional travel experience, leading to increased customer loyalty and positive word-of-mouth. Airlines also have the opportunity to incorporate the latest technological advancements, such as wireless connectivity or interactive touchscreen displays, into their customized Boeing 777 aircraft, further enhancing passenger satisfaction.

One such example is Qatar Airways, which has customized its Boeing 777-300ER with a state-of-the-art Qsuite—an innovative business class product that features private suites, sliding doors, and customizable cabin configurations. This unique offering has earned Qatar Airways multiple awards for its exceptional passenger experience.


The Customer Originated Change (COC) process on the Boeing 777 allows airlines and operators to customize various aspects of the aircraft to meet their specific needs and requirements. This customization not only enables tailored solutions and improved operational efficiency but also enhances the overall customer experience. Boeing’s commitment to customer satisfaction is evident through the COC process, which allows airlines to differentiate their services and create a competitive advantage in the market.

Airlines that choose to make COCs on their Boeing 777 aircraft can optimize performance, increase revenue potential, and provide an exceptional travel experience for their passengers. With the flexibility offered by the COC process, Boeing continues to strengthen its relationship with airlines and operators, ensuring their continued satisfaction with the Boeing 777.
