the Navarrese town of Lesaka and were part of the "commando Elurra" (), previously known as "Goiztiarrak", formed in 2002. Until 2006, the commando had the only task of helping members of ETA cross the Spanish-France border and transporting explosives. The cell was also linked with a car bomb attack against a discothèque in the town of Urdax on February 14, 2006, as well as with another attack against a discothèque in Santesteban on December 21, 2005. The leader of the commando group, Joseba Aranibar alias "Basurde" and Joseba Iturbide, who was also part of the cell, did not take part in the meetings. During the first meeting, Txeroki gave instructions on how to carry out the attack and told the members of the commando which secondary roads they should take to arrive to the airport and avoid being caught by security forces. After the meeting, Sarasola took part in the September 23 event along with Joseba Iturbide and an unknown member of the organisation. In October, Sarasola, Portu and San Sebastián rehearsed the route to the airport twice.

Leaving from Navarre, the commando members succeeded in parking the Volkswagen Polo in the Terminal 4 car park. After the rehearsals, they met again with Txeroki, who gave them the final instructions for the attack, including the day the attack would take place, as well as how to dress on the day of the bombing. Txeroki asked Sarasola to wear a wig, a cap, as well as a face mask on his nose. Sarasola would also have to carry a suitcase and a crutch, pretending to be lame on one of his legs. He also asked Sarasola to buy a mobile phone with which Portu would warn of the bombing, and told them which places they should phone: the DYA headquarters, a Basque roadside assistance association, in Bilbao, Madrid's firemen and the emergency telephone number 112. Nonetheless, Portu would eventually also call a Basque emergency number. On December 27, Portu, Sarasola and San Sebastián stole a Renault Trafic at gunpoint in the French town of Luz Ardiden and held its owner for three days in a cabin located in the Pyrenees. During that time, he was forced to send mobile messages to his mother, stating that
