To ensure that your partnership is successful and beneficial for your network planning, you should conduct a thorough analysis and evaluation of your potential partner and the market. This includes identifying the synergies, gaps, risks, and trade-offs that a partnership entails, as well as setting clear and realistic objectives and expectations. Additionally, it is important to establish a strong and transparent governance and communication structure. Define the roles, responsibilities, and accountabilities of each partner, create a mechanism for resolving conflicts and disputes, and communicate regularly with your partner. Furthermore, align and integrate your network design and operations with your partner's as much as possible. Coordinate schedules, fares, products, and services to offer a seamless experience to customers. Share data, information, and best practices to improve network efficiency. Review and update your partnership periodically to adapt to changing market conditions and customer needs. Evaluate results and impacts of the partnership while being flexible to new opportunities or challenges. Be ready to exit or modify the partnership if necessary.
