According to another forum, Ryanair 8 based units in the internal systems and at least 3 new routes for Summer 2014.
Given the schedules allow for 6, I cant see 8 based coming to fruition as there would have to be some pretty hefty increases and a few new route. There was an allowance for 7 units a few weeks ago but 8, hmmm. Wouldnt want to be in the T3 rush if 8 do happen.
