Please do be very careful not only during the flight but when you claim your pets.I worked at our airport and more than once chased down scaired animals. One got loose and it took 3 weeks to find him and get him cornered to tranqulize him to save him from the freeway and planes. Don't let them out of carriers till you are in a SMALL confined area with doors closed tight then get leashes on quickly and collars tightly on. I know that sounds harsh. I have just seen too many get away,cuz owners don't take these percautions. You never know how your pet will react. Even the most seasoned travelers can have a bad time and get nuts.
