This is the latest advice from the British Embassy for those planning to travel from the UK to Spain.
Anyone returning from England to Spain, must be aware that as of today, Monday March 8, 2021, will need to complete a travel declaration form providing the reason for your journey abroad and confirming that you are legally allowed to travel from England.
You must complete this form if you are travelling outside the UK from England, and you may be fined if you do not.
Different rules apply for international travel from Northern Ireland, Scotland and Wales.
You should print a copy of the completed form or save it to a mobile phone or other device. Carriers will be checking the forms have been completed before boarding.
For further details including information about the legally permitted reasons for international travel and a link to the form, please see:
