By my reckoning in the current Ryanair fleet there are 16 aircraft which are 9 yrs old or more
There are 193 of the 305 aircraft in the fleet which were delivered before the end of 2009.Assuming that 75 of these are replaced by aircraft from the new order by 2018, thiswill leave 118 aircraft of 9 yrs + by the end of 2018 (compared to just 16 now)
