from the KLM press release (http://corporate.klm.com
"From July 1, 2002, KLM passengers will have access to 11 new destinations in Spain, which are linked to KLM’s scheduled flights to and from Madrid and Barcelona through connecting Air Europa flights to and from these destinations. The new KLM codeshare destinations in Spain are: Bilbao, Ibiza, Lanzarote, Las Palmas, Malaga, Menorca, Palma de Mallorca, Santiago de Compostela, Seville and Tenerife (Norte Los Rodeos and Sur Reina Sofia). The new codesharing flights will be sold via the CRS systems from June 25, for flight operations from July 1 2002.
As per August 1, 2002, members of KLM’s frequent flyer programme Flying Dutchman can earn and spend their points on these and many other flights of the Air Europa network, while members of Air Europa’s frequent flyer programme Fidelitas can earn and spend their points on the entire KLM network (except the flights operated to Havana, Santo Domingo and Caracas)."
This is not the entire Air Europa network by far, seems KLM is trying to limit the damage to its Transavia business that might arise from this deal.
