Our business, financial condition and operational results could be adversely affected if we or certain aviation authorities in the countries to which we fly fail to maintain the required foreign and domestic governmental authorizations necessary for our operations. In order to maintain the necessary authorizations issued by the Panamanian Civil Aviation Authority (the Autoridad Aeronáutica Civil, or the "AAC"), the Colombian Civil Aviation Administration (the Unidad Administrativa Especial de Aeronáutica Civil, or the "UAEAC"), and other corresponding foreign authorities, we must continue to comply with applicable statutes, rules and regulations pertaining to the airline industry, including any rules and regulations that may be adopted in the future. In addition, Panama is a member state of the International Civil Aviation Organization, or "ICAO," a United Nations specialized agency. ICAO coordinates with its member states and various industry groups to establish and maintain international civil aviation standards and recommended practices and policies, which are then used by ICAO member states to ensure that their local civil aviation operations and regulations conform to global standards. We cannot predict or control any actions that the AAC, the UAEAC, the ICAO or other foreign aviation regulators may take in the future, which could include restricting our operations or imposing new and costly regulations or policies. Also, our fares are subject to review by the AAC, the UAEAC, and the regulators of certain other countries to which we fly, any of which may in the future impose restrictions on our fares.
We are also subject to international bilateral air transport agreements that provide for the exchange of air traffic rights between each of Panama and Colombia, and various other countries, and we must obtain permission from the applicable foreign governments to provide service to foreign destinations. There can be no assurance that existing bilateral agreements between the countries in which our airline operating companies are based and foreign governments will continue, or that we will be able to obtain more route rights under those agreements to accommodate our future expansion plans. Any modification, suspension or revocation of one or more bilateral agreements could have a material adverse effect on our business, financial condition and results of operations. The suspension of our permits to operate in certain airports or destinations, the cancellation of any of our provisional routes, the inability for us to obtain favorable take-off and landing rights at certain high-density airports or the imposition of other sanctions could also have a negative impact on our business. We cannot be certain that a change in a foreign government's administration of current laws and regulations or the adoption of new laws and regulations will not have a material adverse effect on our business, financial condition and results of operations.
The most active government regulator among the countries to which we fly is the U.S. Federal Aviation Administration, or "FAA". The FAA from time to time issues directives and other regulations relating to the maintenance and operation of aircraft that require significant expenditures. FAA requirements cover, among other things, security measures, collision avoidance systems, airborne wind shear avoidance systems, noise abatement and other environmental issues, and increased inspections and maintenance procedures to be conducted on older aircraft. For example, following the Ethiopian Airlines accident involving a Boeing 737 MAX 8 aircraft on March 10, 2019, we suspended operations of our six Boeing 737 MAX 9 aircraft, after authorities in Panama and other countries grounded the 737 MAX fleet worldwide, during the investigation into the cause of the accident. We partially covered our operation with other aircraft in our fleet, with significant cancellations and delays. On November 18, 2020, the FAA rescinded its grounding order, issued an airworthiness directive, and published training requirements enabling the Company to begin modifying certain operating procedures, implementing enhanced pilot training requirements, installing FAA-approved flight control software updates and completing other required maintenance tasks specific to the MAX aircraft. In January 2021, we resumed operations of our Boeing 737 MAX fleet after the authorization of the AAC. On January 6, 2024, following the Airworthiness Directive issued by the FAA, we suspended operations of 21 Boeing 737 MAX 9 aircraft. From January 6 to January 29, 2024, a total of 1,788 flights were cancelled. After undergoing the technical inspections required by regulators, most of these aircraft have returned to our flight schedule. See "-If we are unable to successfully operate new aircraft due to safety concerns, in particular our new Boeing 737 MAX aircraft, our business could be harmed." If the FAA or the U.S. Transportation Security Administration, or "TSA", were to issue additional regulations on aircraft, our ability to carry out regular operations could be negatively impacted. As we expand our presence on routes to and from the United States, we expect to continue incurring expenses to comply with the FAA's and TSA's regulations, and any increase in the cost of compliance could have an adverse effect on our financial condition and results of operations.
Copa Airlines is authorized by the DOT to engage in scheduled and charter air transportation services, including the transportation of persons, property (cargo) and mail, or combinations thereof, between points in Panama and points in the United States and beyond (via intermediate points in other countries). Copa Airlines holds the necessary authorizations from the DOT in the form of a foreign air carrier permit, an exemption authority and statements of authorization to conduct our current operations to and from the United States. The exemption authority was granted by the DOT in February 1998 and was due to expire in February 2000. However, the authority remains in effect by operation of law under the terms of the Administrative Procedure Act pending final DOT action on the application we filed to renew the authority on January 3, 2000. There can be no assurance that the DOT will grant the application. Our foreign air carrier permit has no expiration date. A modification, suspension or revocation of any of our DOT authorizations or FAA operating specifications could have a material adverse effect on our business.
