Ryanair says it carried 4.66 million passengers last month, an increase of 5% on the same month last year.
The load factor, or percentage of seats filled, was up one point at 71%.
Earlier this week, Ryanair announced a 'disappointing' €10m loss for the three months to the end of last year. The company blamed disruption to services caused by poor weather and air traffic control disputes.
The airline said said its third quarter revenues grew 22% to €746m thanks to a 6% increase in passenger traffic and an average fare increase of 15%. It carried a total of 17 million passengers in the three-month period.
