    Wonderful With Pets

    Allegiant requires that your dog stay under seat in front of you during take off and landing. The rest of the time they can stay in your lap inside carrier. Yay, Allegiant (excellent with pets)!!!

    We flew with ease

    The carrier was quickly scanned by TSA. Allegiant rep quickly looked at carrier for approval. My newly adopted dog was able to sit comfortably on the floor below my feet. The process was so much easier than I expected 😊

    Kind to my pup

    Edward traveled as a pet for several years until a got him registered as my emotional support animal. As long as he was in his bag... everything went well with the staff.
