CONSIDER ALL THE ALTERNATIVES TO FLYING
If you plan to take your pet on vacation, it is generally better to drive. However, if driving is not an option, leaving your pet under the care of a pet sitter or boarding kennel is advisable to ensure their health and happiness. In some cases, you may have no choice but to fly with your pet, in which case you should weigh the risks against the benefits before deciding.
VISIT YOUR VET
Many airlines require a health certificate for pets, which is usually issued within 10 days of travel. This is a perfect time to verify that your pet’s vaccinations are current and that it is not suffering from any illnesses that could worsen due to heat or stress.
RESEARCH YOUR DESTINATION
If you are traveling with your pets internationally or to Hawaii, they may need to be quarantined upon arrival and require import forms. It’s important to familiarize yourself with the specific requirements, including where and for how long they will be quarantined.
If you need to transport your pet by air, it is best to have them travel with you in the cabin. Most airlines allow small dogs or cats to travel in the cabin, but you must call the airline ahead of time to make arrangements and pay any necessary fees. Keep in mind that there are limits to the number of animals allowed in the cabin. If you are flying with a dog, ensure they meet the airline’s size requirements. If you find the regulations overwhelming, some companies can assist you in navigating the process of flying with your furbaby
