In big countries, when people take pets on long domestic trips, they either drive them or fly them. Airlines usually provide options for pets to travel under seats or as cargo - with extra charges of course. In the US, doting pet owners who do not want their pets to travel in such undignified or uncomfortable ways can book them up on a flight with Pet Airways. Their pets may then be treated as valued "pawsengers". As they said in their creative slogans, they are "the first airline with four leg room" and "the first airline where pets fly in the main cabin, NOT in cargo". While on board, the pets get carriers tailored to their sizes, constant attention of the pet attendants and regular potty breaks. And they are available for pick up at the Pet Lounge at the destination 30 minutes after arrival.
Not a bad way to travel for our four-legged friends, huh?
The picture below shows an aircraft Pet Airways use for their flights. Make no mistake about the big puddle of water on the ground. It has absolutely nothing to do with the pets!
