Customer satisfaction, customer loyalty, service adoption, and long-term competitiveness are all strongly impacted by customer happiness, which has become a key component of organisational growth in the transportation industry. The study examines the key factors that influence consumer satisfaction in a variety of transportation contexts, such as roads, trains, airlines, and maritime services. To identify the main factors influencing customer satisfaction, a secondary method was used to gather information from the government websites, industry reports and consumer feedback analysis and various research papers. The results showed that, although price and dependability are key factors in public transportation, comfort as well as premium facilities are crucial in air travel and luxury travel, while safety and sustainability has become universal issues in a post-pandemic and environmentally friendly period. The study concludes that the transport businesses need to take a comprehensive, customer-centred approach that maintains a balance between operational effectiveness, creativity, and social responsibility. The study recommends that the transportation sector should improve in the use of technology, providing employee training, improving comfort features, ensuring open communication, and incorporating sustainable practices.
