Last Christmas, Boris, a dog from Florida, escaped from his cargo crate while in the custody of Delta Air Lines and roamed Queens, New York, for a whole month. The incident raised serious questions about travel and animal safety. Some airlines are more pet-friendly than others, but in the past few years, the U.S. Department of Agriculture has prosecuted cases against most major airlines. Here are some pointers on flying with your pet.

  • Consult your vet. An exam could reveal a medical reason for grounding the animal. The required health certificate is valid only if signed by the vet within 10 days of departure.
  • Contact the appropriate consulates or authorities regarding quarantine and public-safety regulations. England's six-month quarantine is infamous, but Hawaii is not far behind (120 days).
  • Book off-peak, nonstop flights. And even though most cargo holds are climate-controlled, it's best not to risk exposing your pet to extremes in temperature. If you must travel when it's hot, choose an after-dark flight; when it's cold, fly in the middle of the day.
  • To travel with you in the cabin, the pet must stay in a carrier that can fit under the seat ahead of you. Many airlines welcome small animals in the Sherpa Bag, a flexible, soft-sided carrier (800/743-7723).
  • Animals too large for an under-seat carrier have to fly cargo in a shipping crate that meets all USDA requirements. Make sure your pet is wearing a collar (no leash!) with two ID tags; consider purchasing additional tags in a foreign language.
  • Condition your pet to its crate-frantic, cage-shy animals are capable of Houdini-esque maneuvers. Start by putting its favorite toys in there. "Then," says Bash Dibra of Fieldston Pets in Riverdale, N.Y., "make it a flight simulator-turn out the lights and let the pet rest for eight hours at a time. If it can do that, it'll be fine for an eight-hour flight."
  • Never, ever tranquilize. "More animals die as a result of overtranquilizing than of airline negligence," says Kathi Travers of the ASPCA.
