| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | During the period covered by this Annual Report, Air Wisconsin's approach to mitigating information technology (“IT”) and cybersecurity risk was comprised of a range of activities with the primary objective of maintaining the confidentiality, integrity and availability of its critical IT Systems and information related to its business. Although IT Systems are inherently vulnerable to interruption due to a variety of sources, Air Wisconsin aligned its cybersecurity risk management program, including our processes and controls, with certain applicable and relevant guidelines, including the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF). Air Wisconsin assessed its cybersecurity maturity against the NIST CSF’s core functions; however, this did not imply that it met any particular technical standards, specifications or requirements, only that it used the NIST CSF as a guide to help it identify, assess and manage cybersecurity risks relevant to its business. Air Wisconsin's cybersecurity risk management processes included a cybersecurity incident response plan, and it invested in technical and organizational safeguards intended to manage and mitigate material risks from cybersecurity threats to its IT Systems, including network security controls, employee training, internal vetting of third-party vendors and service providers with whom Air Wisconsin may have shared data, and regular system reviews and security exercises. Air Wisconsin's cybersecurity risk management program was a component of its overall enterprise risk management program, and shared common methodologies, reporting channels and governance processes that applied across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas. During the period covered by this Annual Report, Air Wisconsin worked closely with accredited third-party cybersecurity firms to audit its security architecture. Air Wisconsin's Information Security Team, consisting of experienced cybersecurity professionals, was responsible for the day-to-day management of our cybersecurity risks, including directing its cybersecurity risk assessment processes, its security processes, and its response to cybersecurity incidents. For the year ended December 31, 2025, Air Wisconsin did not identify risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that had or were reasonably likely to materially affect it, including its operations or business strategy or our results of operations or financial condition. Air Wisconsin faced certain ongoing risks from cybersecurity threats that, if realized, could have materially adversely affected it, including its operations or business strategy or our results of operations or financial condition.

| Cybersecurity Risk Process for Informing Board Committee or Subcommittee Responsible for Oversight [Text Block] | In the event of a breach or incident, the cybersecurity policies and procedures manual requires notification to Harbor's board of directors. If the board of directors were notified of a cybersecurity breach or incident, it would evaluate the scope and severity of the incident, oversee the response and remediation efforts and assess any disclosure obligations. Following the Aviation Disposition, we engaged a third-party to manage our IT services, including the critical function of end-point protection and overall cybersecurity strategy.
