There will be no snakes on this plane says one US airlines.

Frontier airlines, which is a small US airlines that operators more than 550 flights from Milwaukee’s General Mitchell Internation Airport, Denvers Internation Airport, and Kansas city International Airport, will be charging $75 each way for pets to fly.

Rabits, small dogs, hamsters, guinea pigs, and household birds will be allowed to fly if they are in an approved carrier that fits under the passenger’s seat. Snakes will have to sit this one out, as will insects, spiders and amphibians.

If you have bigger animals that weigh 20 pounds or more they can fly in the tail section of the plane for  $150. The airline in the past allowed pets on their planes but outlawed them for the last two years.

“We have spent a lot of time listening to our customers and determining what would make their travel experience even better,” said Ian Arthur, vice president of marketing and branding.

“We received a lot of feedback on our pet policy and determined that pets would be a welcome addition to the Frontier travel experience.”
