Etihad Airways carries dogs and cats in the cabin up to 8 kg and in the hold. The service is paid: 399 USD per flight. The pet's place is booked in advance — at least 168 h before departure.
Some countries take no animals at all: United States, Hong Kong, United Kingdom, Australia and Taiwan. A separate breed ban applies to 12 breeds. Direct flights reach 59 countries, but flying there and taking a pet are different questions: the destination country has its own entry rules.
