Traveling With Pets The tips below are to make the travel experience easier on both you and your pet. * Your pet must be at least 8 weeks old and fully weaned before traveling. * You must obtain a health certificate issued by a licensed veterinarian for your pet, dated within 10 days prior to travel. * Make sure your lodging accepts pets. * If your pet is small enough (less than 15 lbs) and you have an airline approved carry-on kennel, it might be best to carry your pet on the plane yourself and stow the kennel under your seat. The kennel can be considered carry-on luggage. * If you are trveling with a large pet, make sure its kennel is large enough to allow your pet to stand and move around. * If you need to purchase a kennel, contact your veterinarian or local pet supply store and get recommendations on the best kennel and kennel size for your pet. Be sure the kennel is made for air travel. * Try to book a trip with no connecting flights. * Avoid crowded flights if possible. * It's best if the tempreture at your vacation destination is between 10 degrees and 85 degrees, but there are some exceptions to this.
