Yes, Frontier does allow pets on board, but only small ones that fit in a carrier under the seat. I flew with my cat from Denver to Orlando, and honestly I was nervous because it was my first time bringing a pet on a plane. The booking site wasn’t super clear, so I just called 844-734-0813 to confirm the rules before I paid. The agent explained the fee (about $99 each way) and gave me the exact carrier dimensions, which saved me from showing up with the wrong bag. On the day of travel, check-in was smooth, and my cat actually did fine the whole flight. The key is to plan ahead and double-check the requirements. If you ever need to instantly book, cancel, or modify flights (or ask about pets), that number is definitely the quickest way to get answers.
