The Travellers' Point of Entry (TPE) at Lisbon airport is closed between 00:00 and 06:00 am, so the compulsory veterinary checks on non-commercial pets from countries outside the European Union, carried out through this TPE, will take place outside that time.
A tolerance is understood in the case of flights which, although with an hour of arrival close to but before 00:00, motivate that the animals can only be present for veterinary checks after 00:00.
However, this tolerance only takes place in the case of pets for which notice of arrival has been given by travellers with the advance already established by these services.
