Bulgaria Air does not transport live animals to/from Great Britain. They require passengers to inform the Customer Service Team that they are traveling with their pet at the time of purchase. You can contact them directly at (+359) 2-402-0400. There is no request in advance, so Fido's carriage may be refused after purchase.
