Rabies vaccination certificates that do not contain the above information or that do not match the information on the health certificate upon arrival in the United Kingdom may cause pets to be quarantined at the owner's expense. In my experience, and from what I've heard and seen on the Instagram accounts that I follow with dogs that travel abroad a lot, I've heard that Virgin, British Airways, Lufthansa and Air France are amazing when it comes to traveling with pets. In the case of requirements to travel with pets that are not listed, the foreign country has not officially informed APHIS about the requirements to travel with your pet. To do this, it is necessary to make the necessary arrangements in advance for the pet bird to spend 30 days in quarantine at an authorized center in the United Kingdom upon arrival in the United Kingdom.
Pet owners must travel to the UK within five days of the pet's arrival to prevent the move from being labeled “commercial shipping”.
