“International transit through Spanish airports by passengers on flights departing from the UK is permitted on presentation of a negative PCR, TNA or LAMP test taken within no more than 72 hours prior to arrival into Spain. See Transiting Spain,” the FCDO explained.
Spain has a very strict stance on coronavirus testing for those entering the country.
The FCDO clarifies: “All passengers (excluding children under the age of 6 years old) travelling to Spanish airports and ports from ‘risk’ countries (as determined by the European Centre for Disease Prevention & Control) will be required to present a negative PCR swab test taken within no more than 72 hours prior to arrival, in order to enter the country.
“From December 10, 2020, a TMA (Transcription-Mediated Amplification) swab test or a LAMP (Loop-Mediated Isothermal Amplification) test are also accepted by Spanish authorities, again taken within no more than 72 hours prior to arrival.
