Many airlines require that the dog be given a tranquilizer supplied by your vet. Most veterinarians no longer recommend sedating your animals when transporting by air.
America West and Southwest will take pets, (cats and dogs as cabin pets). There is a charge per direction and they must have a health certificate and fit under the seat . AA, UA and US all take dogs. US charges $30. AA and UA charge $50. (Small dogs.) United charges $50 per carrier for cats in the pet area, $30 for cats as underseat baggage. All carriers require a recent (10 days old or less) veterinary certificate of health, but rarely look at it.
All airlines embargo pets if the outside temperature is in the 90's (or perhaps even 80's). AA won't carry a pet if the temperature is less than 45F (enforcement of this rule is uneven). UA says they won't handle pets when it is -10F. US says they always handle pets except on certain commuter flights. US allows you to bring your pet out to the gate and have it boarded just before you get on the plane. AA sometimes will, but usually won't, allow this.
Because of airline restrictions and the poor ventilation and care available during flights, it is best to refrain from air travel with your dog. Some airlines will allow you to purchase the seat next to your in First Class, allowing the dog to remain in a confined bag or crate, in your full view.
Measure length from the front breastbone to the base of tail plus 6" for medium breeds and 10" for large breeds. Measures height: from the floor to the shoulder. For airline travel, it is not necessary that the crate be as tall as your pet's head. Width is measured the same as height without adding any extra inches.
Traveling by car is the best mode of transportation for a dog. Travel car seats, harness hookups and a product called OG-GONE DEVICE (backpack style car seat) can be useful. The safest option for long distance travel is a hard-shell plastic crate.
