Ancillary revenues grew 8% to €346.3m, or 20% of the airline's total revenues !!
Why? New charge fee allowance

Passengers are now forced to register online for £5 (£10 for a return, £40 if you forget). Also, as a change in Ryanair’s commercial policy, the company has increased the fees it charges to check in bags and sporting equipment by 50%. The airline also increased bag check-in to £15 from £10 when ticket is booked in advance online and to £30 from £20 if you pay at the airport. However, the airline is also changing its baggage policy to allow passengers to take a second bag weighing up to 15kg on payment of an additional fee. The second bag will be charged £35 if booked on the internet and £70 at the airport. Currently, the airline allows passengers to take up to three bags with a combined weight of 15kg with the second and third bags charges at £20 each way.
