Traveling with Pets
Pets that fly with passengers may be accepted as baggage, paying the corresponding fare, if applicable, irrespective of the baggage allowance which the passenger has a right to.
As a general rule, these animals must be checked-in and loaded into the hold of the aircraft, where they will be placed in a container which can be obtained from some airlines.
It is important that when you make the booking or buy the ticket, whether in the airline or travel agency, you state your intention of carrying a pet on board and find out the specific conditions for their transport (identification documentation, vaccination, etc.).
