Thanks gareth. Have tried booking again tonight with more success with same dates i wanted this morning, got a whole list of dates available when looking, but couldnt get it this morning, did same process of booking , maybe a systems problem, (or me!!!haha!). Thanks anyway
* just to add tried booking for feb and march does say no flights and I used a wide date range to check. seems flights have been dropped
* just checked on ryanairs low fares table , last flight bookable is 31jan
