If you listen to Eddie they'll all be long since sold. EasyJet - March 2018 http://www.easyjet.com/en/schedule-release Ryanair - at least 5 (usually 6) months before the flight dates.
I don't like to bash other posters but really factual questions like this should get factual answers. The idea that they release their schedule only 2 months in advance is ludicrous.
I have just made a booking with then within the last hour,booking is available until end of October 2018...however...I have noticed in the past,it depends where you are going,where is it you want to go?
