Staying with your pet in the cabin may, understandably, seem the most reassuring option. But the cabin is often loud and chaotic which is far more stressful for your pet than flying in the quiet and regulated hold. Additionally, this option is only viable for very small animals given they must travel in an airline-approved crate beneath the aeroplane seat. Even so, some routes still have restrictions no matter the size of your pet and many international airlines don’t permit this option at all.
