The Ryanair Group has about 590 aircraft. Examining Cirium schedules data shows that the ultra-low-cost carrier is the worlds fifth-largest operator by summer flights; only American, Delta, United, and Southwest have more. Ryanair is comfortably the market leader in Europe and nearly twice the size of second-ranked easyJet. Ryanair has up to 3,530 daily services this summer and 13% of the continent’s total, a staggering amount for one airline.
