Most airlines allow passengers to bring on small pets. They must be able to fit in a traveling container that will fit under the seat, and have a certificate from a veterinarian stating that the pet is vaccinated and okay to travel.
Most people who travel with their pets have a close, warm relationship with them. They want to hold and cuddle with them, pet them, talk to them. In short, they dearly love their pets. This is not an emotion necessarily shared with other passengers who may be seated around them.
For this reason, airlines have requirements that the pet must remain in the travel carrier. If food or water is needed, this must be placed into the carrier along with the pet. Under no circumstances may the pet be allowed out of the carrier to roam the cabin, play on the floor, or snuggle on a lap.
Flight Attendants, being both human and animal loving kind of people, sometimes overlook this rule. I can guarantee you that an ugly, misbehaving pet will spotted from ten rows away. It is often difficult, however, to see a well-behaved, furry little puppy with big brown eyes that look up at you with love pouring out of its very being. If it’s not purring too loudly, we may occasionally miss noticing that tiny little kitten that has slipped onto a lap or into a pocket. I know, it’s not fair, but some days our eyesight just isn’t what it used to be.
