Ryanair today announced that 5.23 million passengers travelled with the airline in September, a 20% increase compared to September 2007.
Ryanair carried just more than 56 million passengers in the year to September 2007.
Ryanair's head of communications Stephen McNamara said: "Having achieved record passenger numbers throughout the summer, we showed no sign of slowdown in September with 5.23 million passengers taking advantage of Ryanair’s guaranteed lowest fares and no fuel surcharge.
"A lot of price sensitive leisure passengers have switched from rival, high fares airlines, to Ryanair.
"However, in light of the current crisis in banking and financial institutions, we are confident that we will soon seen more bankers migrate to Ryanair also."
