Europe's leading travel search site Skyscanner reported that according to new rules, pot-bellied pigs could be allowed in an aircraft only if owners can prove they provide "emotional support." 

Pet owners these days are becoming more cautious about leaving their beloved pets behind during vacations. 

Special airlines like PetAirways have started limited initial routes which cater only pets; owners are not even allowed in the cargo section of the aircraft.

The U.S. Department of Transport's draft manual on equality for disabled travellers on commercial flights states that small "service" animals should be permitted on flights including sensitive hogs, miniature horses and monkeys.

Miniature horses are very useful for the visually impaired traveler because they're quiet humble and sensitive animal.

But the draft also states that no snakes, spiders or other dangerous creatures, which can be unsafe for other animals, are allowed to board any airline.

Passengers disabilities will not be declined on the basis of any complaints against their pets being on the plane and giving little trouble to fellow passengers.

When PetAirways announced to launch the airline the Co-founder of Skyscanner Gareth Williams commented that, "there's definitely a market for a pet airline; after all, the US spends $41 billion a year on pets, more than the GDP of over half the countries in the world! We are now considering the possibility of adding PetAirways flights to Skyscanner's flight search."

PetAirways must be very happy after this new initiative taken by the US Department of Transport's.

Wendy Ponzo, a spokesperson from the North American Potbellied Pig Association heartily welcomed the news and said that her pet is a very nice, kind and sensible animal. The animal detects her sickness by its sixth sense. 

There are believes that some people will might fake their illness so that they can bring their pets on flights but the draft strictly says that all airlines are allowed to check the documents and verify claims whether the pet has undergone any kind of training or not.
