At the monument the current opening date for the airport in between late November 2011 and January 2012. So if Ryanair were going to use the airport it would not be until March 30 2012.
Ryanair did not cut seven of there nine routes because of a problem with Murcia-San Javier Airport. It was because of Murcian Government failing to promote tourism. Ryanair have no reason to move to the new airport unless they are planning on opening a base there but I wouldn't think they would as Alicante is so near.
