How to Fly Safely With Pets With No Problems?

There are a couple of measures you can take when flying with your emotional support animal, pet, or service animal to ensure you encounter no problems.

Ensure your dog is in perfect health before flying.

It is imperative to ensure your pet is feeling okay, especially if you will travel long flights. If it is an emotional support animal, you need it at its best because seeing it in distress can be more damaging to you.

Take your pet to get checked out and ensure it has not been sick in the last few days.

Get a comfortable and spacious spot

Comfort and space are good things for you and your pet or dog. The front seat is always more spacious, so you might want to book that. Also, ensure your dog carrier is big enough to allow movement to your pet if it gets restless.

The pet should be able to stand up, sit down, and turn around. The more room they get, the more comfortable they will get.

Ensure your dog is well-behaved

Even airlines that accept pets do not allow disruptive pets on board. You need to train your emotional support animal or pet to be well-mannered. If it is an emotional support animal, you want to make sure it is non-disruptive so that you can be allowed to stay with it.

Call your airlines in advance

Different airlines have different pet policies and requirements. Call your airlines in advance to be aware of what is allowed and what is not. This will help to avoid any miscommunication during boarding.

Have the proper and up-to-date documentation

Many airlines require proper documentation, especially for emotional support animals. This is because some people started taking advantage and bringing all kinds of animals on board under the guise of emotional support animals.

If you need to provide proof, have your ESA letter to clear any doubt. Other documentation includes a pet passport, health, or vaccination certificate.
