Airline ratings are assessments that evaluate the quality and safety of airlines based on various criteria. These criteria often include factors such as on-time performance, customer service, cabin comfort, and safety records. Organizations like Skytrax and AirlineRatings.com provide these ratings to help travelers make informed decisions when choosing an airline. Ratings are typically expressed in stars or numerical scores, with higher ratings indicating better performance and service. Travelers can use these ratings to compare different airlines and select the one that best meets their needs for comfort, reliability, and safety during their journey.
