You may have thought that penguins couldn’t fly but after viewing these adorable images you’ll realise that it’s just not true.
And it’s not just penguins that are jet-setting through the skies; ponies, cheetah cubs, turkeys and ducks have all been spotted kicking back in the cabin too.
Animals are popping up increasingly next to travellers on flights and many of them are even getting a free ride.
Animals can sometimes travel to support humans, including creatures classified as an emotional support animal (ESA).
Justine Franks suffers from severe anxiety and a peanut allergy and flies everywhere with her dog, Raleigh.

She says Raleigh, an emotional support dog, serves to help both conditions, WFLA reports
‘I always ask if I can have an aisle seat or if the person I’m flying next to is comfortable with the animal,’ said Franks.
Cats, pigs, ducks, turkeys, squirrels, anyone can register their pet as an emotional support animal and fly for free in America.
Passengers with allergies say it’s frustrating and the pet population on planes is getting out of control.

ESAs can be any species, they do have legal protection under the Fair Housing Act and only require a letter from a doctor. There is no legal registry or certification for them and airlines do not have to allow them on board, Newsweek reports
However, a certified service animal is afforded more rights and the U.S. Americans with Disabilities Act officially recognizes only dogs and miniature horses, as eligible for service animal certification.
They must also be trained to perform a specific task, like guiding the blind or alerting their owners of an upcoming seizure.
Service animals have more protections than ESAs, as many people physically require them to help them.
It is not clear whether the animals in these pictures had a specific responsibility to perform on board, or whether they were just been along for the ride.
