Airline reputation refers to how passengers perceive an airline based on various factors, including service quality, safety records, and customer satisfaction. It can be influenced by online reviews, social media feedback, and industry rankings. A strong reputation often leads to increased customer loyalty and higher ticket sales.

Airlines like Delta Air Lines and Singapore Airlines are often recognized for their excellent service, while others may struggle with negative perceptions due to frequent delays or poor customer service experiences.
