Ryanair is consistently one of the world's most profitable airlines due to its ruthless adherence to a Low-Cost Carrier (LCC) business model centered on "ultra-efficiency." One of their primary strategies is maintaining a standardized fleet, consisting almost entirely of Boeing 737 aircraft. This drastically reduces costs for pilot training, cabin crew familiarization, and mechanical maintenance, as they only need to stock parts for one type of plane. They also maximize "aircraft utilization" by keeping turnaround times on the ground as short as 25 minutes, meaning their planes spend more time in the air earning money. Furthermore, Ryanair frequently flies into secondary airports (like London Stansted instead of Heathrow), which are much cheaper to operate out of and often provide the airline with subsidies to bring in tourists. A massive portion of their profit actually comes from ancillary revenue—the "extra" fees they charge for everything from checked bags and seat selection to onboard snacks and priority boarding. By unbundling the fare, they can advertise incredibly low "base prices" to attract customers, then collect high-margin profit on the add-ons. Their digital-first approach also minimizes overhead, as almost all sales and check-ins are handled via their app and website rather than by expensive counter staff.
