TAP Air Portugal carries dogs and cats in the cabin up to 8 kg and in the hold up to 45 kg. The service is paid: 78 EUR per flight. The pet's place is booked in advance — at least 24 h before departure.
Some countries take no animals at all: United Kingdom. Snub-nosed breeds are not accepted in the hold. A separate breed ban applies to 5 breeds. Direct flights reach 36 countries, but flying there and taking a pet are different questions: the destination country has its own entry rules.
