Ryanair has utilized a low-cost business model since 1985 to become Europe's largest airline. Key elements of Ryanair's strategy include maintaining extremely low fares, costs, and operating efficiencies through measures like direct point-to-point routes, online booking, and secondary airports. Ancillary revenues from fees and onboard sales have become a major part of Ryanair's revenue model at 58% as the airline focuses on frequent, low-cost flights while minimizing customer service costs. Ryanair's strategy has been highly successful but maintaining sustainability will depend on continued cost controls and exploiting new growth opportunities like additional routes and destinations.
