Irish low-cost airline Ryanair said on Wednesday its load factor was 86 percent in September, compared with 87 percent a year earlier.

Ryanair also said its passenger numbers in the month rose 17 percent to 3.5 million.

Ryanair said last month the disruption caused by tougher security measures introduced at British airports in August were not affecting passenger demand.

Ryanair upped its profit guidance on September 29 due to better than expected passenger growth, expectations for more stable ticket prices in winter and a lower than expected cost of hedging its fuel bill.
