More than 200,000 people now carry the Ryanair credit card launched in February 2003, the airline said today.
It also reported that applications had been arriving at a rate of 2,500 per week.
The Ryanair credit card allows users a free flight on more than 140 Ryanair routes across 16 European countries. Other benefits include a further free flight when five flights are booked and paid for within one year.
