Ryanair is set to introduce four new routes from Madrid next month.
Ryanair flights to Alicante, Plama, Santiago and Valencia will be introduced from November 18th 2008.
The announcement follows the purchase of two new aircraft by the carrier which will help it deliver these new services.
Michael O’Leary, chief executive at Ryanair, said: "Ryanair is delighted to announce two new aircraft, four new routes and 75 new weekly frequencies at Madrid.
"Only Ryanair guarantees the lowest fares and no fuel surcharge and Ryanair will continue to offer Spanish consumers competition and choice over the high fares and fuel surcharges which Iberia has imposed on them on domestic routes for so many years now."
Meanwhile, rival airline Iberia recently abandoned flights between the Spanish capital and Gibraltar. The last service was on September 28th.
