What happens if I am detained at a Spanish airport on a Red Notice while in transit?

Transit detentions are common at Madrid-Barajas and Barcelona-El Prat airports. Spanish border police have full access to Interpol databases and will detain you even if Spain is not your final destination. You will be brought before the Audiencia Nacional within 72 hours for a detention hearing. Bail is possible but rarely granted in transit cases due to flight risk concerns. Immediate legal intervention is essential to argue for release pending the extradition hearing or to challenge the notice validity directly with the CCF while detained.
