The airline said delivery of an existing Boeing order and increased use of older aircraft would allow it to grow faster.
Without the need for an additional large plane deal.
That's been a source of tension in the past week.
Europe's largest low-cost carrier abruptly ended talks with the U.S. planemaker over a new order for the larger 737 MAX 10 jets.
The deal worth tens of billions of dollars fell apart due to differences over price.
Chief Executive Michael O'Leary told an analyst call after Ryanair's annual general meeting "if we don't do another order until 2025, frankly we couldn't care less."
Shares in the airline jumped 7% on Thursday after it raised the passenger growth forecast.
O'Leary says he has enough planes to fly 225 million people by 2026, up from 200 million in earlier forecasts.
Ryanair said the boost to its passenger forecast reflected large pent-up demand in Europe, and the gaps that have appeared as rivals fail or cut capacity.
The Irish airline, one of Boeing's biggest customers, said it would keep talking to the U.S. giant.
Adding that relations between the two remain "very good."
